When unpolarised light is incident on a medium of refractive index 1.73 at Brewster's angle then reflected light is completely polarised. Using Brewster's Law μ=tan(ip)1.73=tan(ip)ip=60∘ By Law of reflection, ip=r=60∘
An unpolarized light beam travelling in air is incident on a medium of refractive index 1.73 at Brewster's angle. Then -
