When light is incident on a transparent dielectric at the Brewester angle `(tan theta_(p)  =n)`, the reflected light proves to be completely polarized. Is the refracted light also completely polarized in this case?

Explanation

To solve the problem, we need to analyze the behavior of light when it is incident on a transparent dielectric at the Brewster angle.

### Step-by-Step Solution:

1. **Understanding Brewster's Angle**:
Brewster's angle (θp) is defined as the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. At this angle, the reflected and refracted rays are perpendicular to each other. The relationship is given by:
\[
\tan(\theta_p) = n
