Find the angle of refraction for a ray of light falling on a transparent medium of refractive index 1.6.
The reflected and refracted rays are perpendicular to each other.

Explanation

To find the angle of refraction for a ray of light falling on a transparent medium with a refractive index of 1.6, given that the reflected and refracted rays are perpendicular to each other, we can follow these steps:

### Step 1: Understand the Relationship
When the reflected and refracted rays are perpendicular, the angle of incidence (denoted as \( i \)) is known as the polarizing angle (denoted as \( i_p \)). According to Brewster's Law, the tangent of the polarizing angle is equal to the refractive index of the medium.

### Step 2: Calculate the Polarizing Angle
Using Brewster's Law:
\[
