Answer

If light Ray's doesn't bend it is called Reflection
if the light Ray's bend then it is Refraction

Answer

The bouncing back of light from any opaque object is called reflection

Answer

Difference Between Reflection and Refraction. The phenomenon of a light beam rebounding after hitting a surface is called reflection. ... There's another phenomenon called refraction. Here, the light changes direction, or 'bends' as it passes through the boundary between these two media.

But Total Internal reflection occurs only when light travels from a denser medium to a lighter medium. ... Total internal reflection occurs only if the angle of incidence is more than the critical angle between the two media. 4. Only a part of the total energy in the light is reflectedduring the normal reflection.

Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.

Reflection and Refraction: Key Differences

Reflection and refraction are two fundamental phenomena that occur when light interacts with different materials or surfaces. Although they both involve the behavior of light, there are several key differences between reflection and refraction. Let's explore these differences in detail:

1. Definition:
- Reflection: Reflection refers to the bouncing back of light or any other wave when it encounters a surface or boundary that does not absorb the energy of the wave. The angle of incidence (incoming ray) is equal to the angle of reflection (outgoing ray) with respect to the normal, which is an imaginary line perpendicular to the surface.
- Refraction: Refraction is the bending of light or any other wave as it passes from one medium to another with different optical densities. This occurs due to a change in the speed of light, causing the direction of the wave to change. The bending is governed by Snell's law, which relates the angles and refractive indices of the two mediums involved.

2. Light Path:
- Reflection: In reflection, the incident light ray returns back into the same medium after interacting with the surface. The angle of incidence is equal to the angle of reflection.
- Refraction: In refraction, the incident light ray passes from one medium to another and changes its direction. The angle of incidence and the angle of refraction are generally different.

3. Wave Speed:
- Reflection: Reflection does not involve any change in the speed of the wave. The speed remains the same before and after reflection.
- Refraction: Refraction involves a change in the speed of the wave as it passes from one medium to another. The change in speed causes the light to bend.

4. Index of Refraction:
- Reflection: Reflection does not depend on the refractive index of the medium. It only relies on the surface characteristics and the angle of incidence.
- Refraction: Refraction depends on the refractive indices of both media involved. The refractive index determines how much the light will bend when crossing the boundary between the two media.

In conclusion, reflection and refraction are distinct phenomena with different characteristics. Reflection involves the bouncing back of light, while refraction refers to the bending of light as it passes through different media. The light path, wave speed, and dependence on refractive indices are some key differences between these two phenomena. Understanding these differences is crucial in various applications, such as optics, photography, and the design of optical devices.
