Question

What is refraction? Define it's laws?​

Answer 1

Answer:

The change in direction or bending of a light wave passing from one transparent medium to another; caused by the change in wave’s speed is known as “Refraction"

Laws:-

• The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane.
• The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant
