What is the speed of light in a denser medium of polarising of polarising angle `30^(@)`?

Explanation

To find the speed of light in a denser medium at a polarizing angle of \(30^\circ\), we can follow these steps:

### Step 1: Understand the Concept of Polarizing Angle
The polarizing angle (Brewster's angle) is the angle at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. For a polarizing angle \( \theta_p \), the relationship between the refractive indices of the two media is given by:
\[ \tan(\theta_p) = \frac{n_2}{n_1} \]
where \( n_1 \) is the refractive index of the first medium (air, approximately 1) and \( n_2 \) is the refractive index of the denser medium.
