Question

state the laws of refraction​

Answer 1

Answer:

• When a light ray goes from optically denser medium to optically rarer medium then it fastens and bend away from the normal.

Answer 2

Answer:

• The incident ray, the refracted ray and the normal at the point of incident, all lie in same plane.
• The ratio of sine of angle of incidence i to the sine of angle of refraction r is constant for the pair of given medium.

Explanation:

• Sin i/sin r = constant u (mew)
• Constant u is refractive index
