Question : 40 of 73

Marks: +1, -0

Write a relationship between angle of incidence and angle of refraction for a given pair of media.

Solution:

The ratio of the sine of angle of incidence '

i

' to the sine of angle of refraction '

r

' is constant for the pair of given media. This constant is called the refractive index.

{ }_1 µ_2=\;{ sin \;i}/{ sin \;r}
