Answer to Question #164097 in Optics for Sanamtha

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

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