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 determine whether the refracted light is completely polarized when light is incident on a transparent dielectric at the Brewster angle, we can follow these steps:

### Step 1: Understand Brewster's Angle
Brewster's angle, denoted as \( \theta_p \), is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric material, with no reflection. The relationship is given by:
\[ \tan \theta_p = n \]
where \( n \) is the refractive index of the dielectric.
