Case : Read the passage and answer the question(s).

When light is incident at polarizing angle at the interface of a refracting medium the refractive index of the medium is equal to the tangent of the polarizing angle. The angle of incidence of light, at which when ordinary light is incident on transparent refracting medium, the reflected light becomes maximum rich in plane polarized light is called polarizing angle.

A ray of light is incident at polarizing angle. What is the angle between the reflected ray and refracted ray ?

π/2

It is further concluded from Brewster's Law that when a ray of light is incident at polarizing angle the reflected ray is normal to the refracted ray.
