The critical angle for total internal reflection for a substance is `45^@` . What is the polarizing angle for this substance?

Explanation

To find the polarizing angle for a substance given that the critical angle for total internal reflection is \( 45^\circ \), we can follow these steps:

### Step 1: Understand the relationship between critical angle and polarizing angle
The polarizing angle (\( \theta_p \)) is related to the critical angle (\( \theta_c \)) by the formula:
\[ \tan(\theta_p) = \frac{1}{\sin(\theta_c)} \]
