Answer:
The angle of refraction θ₂ = 40.51 degree
Explanation:
given data
ray incident = 60 degree
refractive index of water = 4/3 = 1.333
solution
we will use here Snell's law that states as
n₁ sin θ₁ = n₂ sin θ₂ .....................1
here we take refraction of air n₁ = 1
so put value in equation 1 we get
1 × sin60 = 1.333 × sinθ₂
sinθ₂ = 0.6496
θ₂ = 40.51 degree
