Answer 2

Hey dear,

● Answer -
The change in DIRECTION of light rays while going from one medium to another is called refraction.

● Laws of refraction -
- The incident ray, refracted ray & normal to reflecting surface all lie in same plane.
- For given pair of media, ratio of sine of incident angle to sine of refracted angle is constant.
According to Snell's law -
μ = sin(i) / sin(r)


Hope this helps you...
