Question

what is the causes of refraction of light?​

Answer 1

Answer:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction.

Answer 2

Explanation:

♡♡♡ Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. ...

This concept is often termed the law of reflection.♡♡♡♡
