Critical angle for a certain wavelength of light in glass is 30°. Calculate the polarising angle and the angle of refraction in glass corresponding to this.

Explanation

To solve the problem, we need to calculate the polarizing angle and the angle of refraction in glass given that the critical angle for a certain wavelength of light in glass is 30°.

### Step-by-Step Solution:

1. **Understanding the Critical Angle**:
The critical angle (IC) is the angle of incidence above which total internal reflection occurs. It is given as 30°.

2. **Finding the Refractive Index (μ)**:
