What happens when light enters from one medium to ... moreanother? Does it still move in a straight line ?

Question

Answer

In this situation it bend toward normal

Answer

It will bend toward the normal

Answer

but we know that light move in a straight line

Answer

Yup it's shows refraction means it's bend towards the Normal.  after that ray of light travel in straight line

Answer

It is move in straight line but it deviate from it path

Answer

ya light move in straight lines but when it travel in same medium whenever light travel from one medium to another its velocity change due to which its inital path of ray will change .

Answer

it depend upon the light in  which medium less or more denser according to it expand or bend towards normal

Answer

No due to refraction light bends
when light moves from rarer to denser,it moves towards normal & in case of denser to rarer away from normal

Answer

It deviated there original path

Answer

When light enters one from other medium its get refracted..........yes....if light falls perpendicular toh the surface otherwise nooo is cant still move in straight line....

Answer

No it change its direction and this is called refraction
if light travel from less denser to high denser it bends toward normal and if high to low denser away from normal

Answer

No

Answer

When light travell from one medium to another then speed of light changes. And it may travell in straight line if the light fall at 90*.

Answer

Light gets dispersed due to dependence of refractive index on wavelength.

Answer

Just remember that light is in hurry and it tries to find the quickest path for which it turns towards the normal because the straight line is the quickest path

Answer

No it changes its path because of change of speed and as we know that light takes the quickest path so it bends to travel quickly.

Answer

light will travel in straight line but take a little turn ( critical angle) toward or against normal depending on optical density

Answer

When light enters from one medium to another  then ....if the medium is denser then it bend toward the normal and if the medium is rarer then it away frm the normal ...

Answer

No,it's change its direction when it travel from one medium to another.it move toward normal in denser and away from normal in rarer medium

Answer

The light under goes refraction
we cannot tell whether it bends towards the normal or away form the normal

Answer

yes it still move in a straight line but changes its direction nd thus this phenomenon is known as refraction of light

Answer

Light will bend always when it enters from one medium to another.

Answer

No it will not move in straight line it gets retracted....

Answer

No.... light bend when enters from one medium to another medium....

Answer

Refraction

Answer

No if it is changing medium it will change by following ways:
:: If medium is rarer the light will go away from normal
:: If it is denser the light will travel towards the normal.

Answer

no its bent and refraction of light occur because of medium change.

Answer

When light rays falls on one medium then it bents towards normal and after that more , if rays are get refracted by more media then once time come the ray of light goes straight path.

Answer

It doesn't move in a straight line...hmm..u r right that light must follow Fermat principal but speed of light changes from medium to another soo light move away or move towards the normal

Answer

No, it does not move in a straight line,if it is fall obliquely (means in a certain angle other than 90) it bends away or toward the normal. (and light travels in a straight line in a same medium.)

Answer

It gets bend towards or away from the normal

Answer

No, it will not move in straight line. It will show refraction. Either it will bend towards normal or away from normal with respect to rarer and denser medium.

Answer

No. what happens is it bends towards the normal or get away from the normal , bending of light when going from one medium to another depends on the nature of medium whether it is rarer or denser.

if light is entering from rarer to denser medium then it will bend towards the normal but if it is entering from denser to rarer medium then it would probably get away from the normal.

hope that it would help you.

Answer

no it bends towards the normal

Answer

who?

Answer

if medium is dfrnt and it enters rarer to denser then it bends towards normal but if it enters denser to rarer then it bends away from the normal.

Answer

No the light does not move in a straight line

Answer

If it moves in a straight line, then refractive index of both
medium must be same or the ray should travel perpendicular to the interface.
and if it moves away or towards the normal it is because of refraction.

Answer

You saw that light bends toward the normal in this situation, and that the angle in the denser medium will be smaller than the angle in the rarer medium. ... When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left.

Answer

When light enters from one medium to another medium then refraction will take place.
No, the light will not travel straight because there will change in the direction of light at the interface between the two medium.

Answer

it will bend towards the normal

Answer

no it will not move in a straight line. if the light enters from lighter medium to denser medium it will bend towards the normal and if light enters from denser to rarer medium it will bend away from the normal

Answer

No.... When the light enters from one medium to another it will get refracted....

Answer

It will remain straight in same medium but it will bend in anotherv medium .If light travels rarer to denser medium it bends towards the normal ,if it travels denser to rarer it goes away the normal

Answer

No. It doesn't move in the same straight line. It undergoes refraction. When it moves from a rarer medium to denser medium it moves towards the normal. When light travels from denser to rarer medium it bends away from the normal.

Answer

it will refract towards or away from the normal but when light will pass perpendicularly there will be no change

Answer

Refraction and yes

Answer

it doesn't move in straight line, it deviates

Answer

1. when light travels from rarer medium to denser medium it bends towards the normal.
2. when light travels from denser medium to rarer medium it bends away from the normal.
3. If light is normal to the boundary no refraction takes place.
4. If both the medium have same refractive index then no refraction takes place.

Answer

It bends towards normal

Answer

No it does not move in a straight line ,as when it passes from one medium to another then refraction held .

Answer

The rays changes its angle and bends this is called refraction. no it doesn't move still in a straight line

Answer

No , this phenomenon of light is called refraction

Answer

When light enters from a medium to another medium it bends

Answer

When light goes from 1 medium to another its speed as well as direction will change
but if it fall perpendicularly no change takes place

Answer

The path of the ray gets changed as the medium changes.....it moves towards the normal if its entering a denser medium.....while coming from a rarer medium and vice versa.....it is due to the change in the speed of light ray...

Answer

It depend on the density of medium if it is denser it tends to move toward normal if it is rarer then it will move away from normal

Answer

When light travels from one medium to another it refracts or bends(if they have different densities). No, it does not.

Answer

No it move towards rare to denser medium.

Answer

No , it will not move in a straight line. Due to refraction it will bend .

Answer

No it bends

Answer

Gets refracted

Answer

No .
If the lght travels from a rarer medium to a denser medium then it bends towards the normal .
If the light travels from a denser medium to a rarer medium the it moves away from the normal.
All this happens due to REFRACTION .

Answer

If the light falls perpendicular to the denser medium then the light goes straight.
If angle of incidence = angle of refraction then also light goes straight.
But in all other cases light moves from rarer medium to denser medium or denser medium to rarer medium bending light towards the normal and away from normal respectively.

Answer

No,it changes its angles and moves towards the incident (due to refraction).

Answer

No,it will not go in straight line. This is due to change in velocity of the light as it enters from one medium to another.

If light goes from denser medium to rarer medium then it bends away from the normal and if it goes from rarer medium to denser it bends towards the normal.

Answer

No, the light will refract
it will either move towards the normal if it is moving from a denser to a denser medium
OR
it will move away from the normal if it is moving from a denser to a

Answer

Whenever ligt rays enter from one medium to other , their velocity is changed suddenly, so their direction of propagation also changes, this phenomenon is called Refraction. Reason for refraction is ''difference in the densities of 2 media''

Answer

It bends towards normal...

Answer

NO, LIGHT ENTERS FROM ONE MEDIUM TO ANOTHER ITS VELOCITY CHANGES DUE TO CANGE IN DENSITY OF MEDIUM
(A). IF LIGHT ENTERS DENSER MEDIUM FROM REARER IT'S VELOCITY DECREASES
(B). WHEN IT ENTERS REARER MEDIUM FROM DENSER MEDIUM ITS VELOCITY INCREASES

Answer

When light pass through from one medium to another end it will be bend because light particles speed low in medium but when it pass in 90 degree at a medium it will be go straight

Answer

No the direction of light rays changes due to refraction phenomenon

Answer

Introduction:
When light enters from one medium to another, its path may change due to the change in the optical properties of the medium. The behavior of light at the interface between two different media is described by the laws of reflection and refraction.

Reflection:
When light encounters an interface between two media, a portion of the light is reflected back into the original medium. This reflection occurs due to the interaction between the electric field of the light wave and the charged particles in the material. The angle of incidence is equal to the angle of reflection, and the reflected light travels in the opposite direction to the incident light.

Refraction:
Refraction is the bending of light as it passes from one medium to another with different optical properties. The change in the speed of light causes the change in direction. The amount of bending depends on the angle of incidence and the refractive indices of the two media. The refractive index is a measure of how much slower light travels in a medium compared to vacuum.

Snell's Law:
The behavior of light during refraction is described by Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the velocities of light in the two media. Mathematically, it can be expressed as: n1sinθ1 = n2sinθ2, where n1 and n2 are the refractive indices of the two media, and θ1 and θ2 are the angles of incidence and refraction, respectively.

Change in Direction:
When light enters a medium with a higher refractive index, it bends towards the normal (an imaginary line perpendicular to the surface). This causes the light to change direction towards the interface. Conversely, when light enters a medium with a lower refractive index, it bends away from the normal, resulting in a change of direction away from the interface. However, the light still travels in a straight line within each medium, but its overall path may be altered due to refraction.

Total Internal Reflection:
If the angle of incidence is large enough, the refracted angle can become greater than 90 degrees. In such cases, total internal reflection occurs, and all the light is reflected back into the original medium, with no transmission into the second medium. This phenomenon is utilized in various optical devices such as fiber optics.

Conclusion:
In summary, when light enters from one medium to another, it may undergo both reflection and refraction. The angle of incidence, refractive indices of the media, and Snell's law determine the direction and amount of bending. While the light may change its direction upon entering a new medium, it still moves in a straight line within each medium, unless affected by other factors such as scattering or absorption.

Answer

It gets refracted

Answer

When light move from one medium to another medium it changes or deviates it's direction
and this concept is called refraction.

Answer
