Question

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

Answer 1

Refractive index of glass, μ = 1.5

Brewster angle = θ

Brewster angle is related to refractive index as:

tan θ = μ

θ = tan⁻¹ (1.5) = 56.31°

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