Does the critical angle depend on the wavelength of the light ?

Explanation

To determine whether the critical angle depends on the wavelength of light, we can follow these steps:

### Step 1: Define Critical Angle
The critical angle (θc) is defined as the minimum angle of incidence at which total internal reflection (TIR) occurs when light travels from a denser medium to a rarer medium.

### Step 2: Use the Formula for Critical Angle
The relationship between the critical angle and the refractive index (ν) of the medium can be expressed using the formula:
\[ \sin(\theta_c) = \frac{1}{\nu} \]
