Question:

What is the Brewster angle for air to glass transition? (Refractive index of glass = 1.5.)

Answer:

Given that,

Refractive index of glass, µ = 1.5

Brewster angle = θ

Brewster angle is related to refractive index as: tanθ = µ, θ = tan-1(1.5) = 56.31°

Therefore, the Brewster angle for air to glass transition is 56.31°.
