Question

What is meant by (a.) polarization by reflection and (b.) angle of polarization?

    Ca!calculate the angle of polarization for water of refractive index 1.33. 

Answer 1

Answer

angle between the reflected and refracted ray is called the Brewster angle or polarization angle.

Angle of polarization is given by the $\theta=tan^{-1}(\mu)$ .

If refrective idex with respect to water is 1.33 then ange of polarization will be

$\theta=tan^{-1}(1.33) \\\theta=53.06°$
