Question 8

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°.**
