Question

a ray of light goes from air into a medium with angle of incidence is 60. if the light ray refract in the medium at the angle of refraction 30 . find the refractive index of medium​

Answer 1

Answer:

Refractive Index=sin60/sin30

=sin 60=√3

=sin 30=1/2

Refractive index=√3/1/2

=√3×2/1

Refractive index=2√3
