The ratio of the intensities at minima to maxima in Young's double slit experiment is `9 :25.` Find the ratio of the widths of the two slits.

Explanation

To solve the problem, we need to find the ratio of the widths of the two slits in Young's double slit experiment given the ratio of the intensities at minima to maxima is 9:25.

### Step-by-Step Solution:

1. **Understanding the Given Information**:
We know that the ratio of the intensities at minima to maxima is given as:
\[
\frac{I_{min}}{I_{max}} = \frac{9}{25}
