Find the dispersive power of flint glass. The refractive indices of flint glass for red, yellow and violet light are 1.613, 1.620 and 1.632 respectively.

Explanation

To find the dispersive power of flint glass, we can follow these steps:

### Step 1: Understand the formula for dispersive power
The dispersive power (ω) is given by the formula:
\[ \omega = \frac{\mu_v - \mu_r}{\mu_y - 1} \]
where:
