Question

14. Describe the laws of refraction of light. (2013, 15)
or
Write the Snell's law related to refraction of light.
Or
Write down the Snell's law of refraction. [2019]
Ans. There are two laws of refraction of light:
(i) The incident ray, the refracted ray and the
normal to the interface of two transparent
media at the point of incidence, all lie in the
same plane.
(ii) The ratio of sine of angle of incidence to the
sine of angle of refraction is a constant, i.e.
sin i
(u or n) constant
sin r
It is also known as Snell's law and that constant is
called refractive index (u).​
