Question

State the law of refraction

answer in 2 to 3 lines quickly plzz​

Answer 1

Answer:

laws of refraction :

1) whenever the light goes from one medium to another the frequency of the light doesn't change

2) The incident ray , refracted ray and the normal lie on the same plane

3) The product of refractive index and sine of angle of incidence at a point in a medium is constant

i.e n sin I =constant

Answer 2

Answer:

The laws of refraction are

(i) The incident ray, the refracted ray and the normal all should lie in the same plane

(ii) The ratio of the sine angle of incidence to the sine angle of refraction is constant for the two given media

$\mathsf{ \Large{ \frac{\sin i}{\sin r} = \mu^a_b}}$
