Question

Refraction and reflection of light 0 learn

Answer 1

Reflection:-

When a ray of light falls on any surface, a part of the light is sent back to the same medium. This phenomenon where the incident light falling on a surface is sent back to the same medium is known as reflection.

Reflection of light follow laws of reflection

 

Refraction:-

Refraction occurs when light waves travel from a medium with a given refractive index to a medium with another at an angle. At the boundary between the media, the wave’s phase velocity is altered, usually causing a change in direction. Its wavelength  increases or decreases but its frequency remains constant.

Refraction  of  light follow Snell’s Law.
