What is the angle of dispersion between red and violet colours produced by a flint glass prism of refracting angle `60^(@)`? Refractive indices of the given prism for red and violet colours are 1.622 and 1.663, respectively.

Explanation

To find the angle of dispersion between red and violet colors produced by a flint glass prism, we can follow these steps:

### Step 1: Understand the Formula for Angular Dispersion
The angle of dispersion (Δ) between two colors can be calculated using the formula:
\[ \Delta = (n_v - n_r) \cdot A \]
where:
