A ray of light is incident on a substance of refractive index n at an angle of incidence 60•.If the angle of refraction was 30•,find n2?

Answer 1

Snells Law: n₁sinθ₁=n₂sinθ₂

n₁=n

θ₁=60

θ₂=30

nsin60=n₂sin30

nsin60/sin30=n₂

if the light is starting in air we can use n=1.00 making n₂=1.73, if it isn't specific it is 1.73n where n is the refractive index of the initial material.
