Question

The relationship between Brewester angle ‘θ’ and the speed of light ‘v’ in the denser medium is ______.

Options

• v tan θ = c

• c tan θ = v

• v sin θ = c

• c tan θ = v

Answer 1

The relationship between Brewester angle ‘θ’ and the speed of light ‘v’ in the denser medium is v tan θ = c.

Explanation:

At Brewster’s angle, tan⁡ θ = μ (refractive index)

Since, μ = `c/v`,

we get,

tan⁡ θ = `c/v`

∴ v tan θ = c
