A ray of light is incident on one face of a prism `(mu = 1.5)` at an angle of `60^(@)`. The refracting angle of the prism is also `60^(@)`. Find the angle of emergence and the angle of deviation. Is there any other angle of incidence, which will produce the same deviation?

Explanation

To solve the problem step by step, we will use Snell's law and the properties of the prism.

### Step 1: Identify the given values
- Refractive index of the prism, \( \mu = 1.5 \)
- Angle of incidence, \( i = 60^\circ \)
- Refracting angle of the prism, \( A = 60^\circ \)

### Step 2: Apply Snell's Law at the first surface
