Question

For what angle of incidence will light incident on a bucket filled with liquid having
refractive index 1.5 be completely polarized after reflection ?
​

Answer 1

Brewster's angle(Angle between Reflected and Refrected ray from the glass is 90

tanθ= n 1/n 2

n 2 =1.5

n 1 =1 for air

θ=56.30
