Question

if the angle of incidence equal to angle of refraction then the optical density of​

Answer 1

Answer:

(i) The ratio of the sine of angle of incidence 'i' to the sine of angle of refraction 'r' is constant for the given pair of media. This constant is called the refractive index.

μ=

sinr

sini

(ii) It occurs due to change in speed of light as it enters from one medium to other medium having different optical density.

(iii) When a ray of light is incident normally on the surface of second medium, it passes undeviated.
