Accepted Answer

Light bends towards normal as it moves from an optically rarer to denser medium.

Answer

When light enters from air to glass , the difference of density between air and glass make the ray bent towards the normal . The reason of this bending of light is difference is velocities of light in the two different media .!!.

Answer

When light travel in air it is easy for light to travel easily in air because there are many few restriction but when it enters in glass it have to face a lot of restrictions and its speed is reduced so it bands towards normal.I hope it's help u bro😎

Answer

Explanation:
When light travels from one medium to another, its path may change due to the change in the speed of light. This phenomenon is known as refraction. Refraction occurs at the boundary between two media when the light passes from one medium to another medium with a different refractive index.

In the case of light traveling from air to glass, the refractive index of air is lower than that of glass. When light enters the glass, it slows down due to the higher refractive index of glass. The change in speed causes the light to change direction, or bend.

The direction of bending of light depends on the angle of incidence and the refractive indices of the two media. The angle of incidence is the angle between the incident ray and the normal, which is an imaginary line perpendicular to the boundary between the two media.

Explanation of Options:
a) Light bends towards the normal: This is the correct option. When light travels from air to glass, it bends towards the normal. The angle of refraction is smaller than the angle of incidence.
b) Light proceeds undeviated: This is not correct. Light does not continue in a straight line when it enters a different medium, but rather changes direction.
c) Light bends at 90°: This is not correct. The angle of refraction is generally different from 90°.
d) Light bends away from the normal: This is not correct. When light travels from air to glass, it bends towards the normal, not away from it.

Conclusion:
When light travels from air to glass, it bends towards the normal. This is because the refractive index of air is lower than that of glass, causing the light to slow down and change direction.

What happens when white light is passed from air to glass prism?

Madhu moves towards south-east a distance of 7 km then she moves towards west and travels a distance of 14 m. From here she moves towards North-west a distance of 7 km and finally she moves a distance of 4 km towards East and stood at that point. How far is the starting point from where she stood?

Arun travels 30 km towards East took a right turn and travels 40 km. Then he took a left turn and traveled 30 km. In which direction is he now from the starting point?

Places A and Bare 100km apart on a highway. One car start s from A and another from B at the same time. If the cars travel in the same direction at different speed s,they meet in 5 hours. If they travel towards each other , they meet in 1 hour.What are the speed of the two cars?
