A ray of light falls on a material body ...

A ray of light falls on a material body at an incident angle `60^(@)` and refracted at angle `30^(@)`.
What is the refractive index of the material?

Text Solution

Verified by Experts

Refractive mdex of matenal `=(sin i)/(sin r)=(sin 60^(@))/(sin 30^(@))=(sqrt(3)//2)/(1//2)=sqrt(3)`
