Find the ratio of intensity of maxima and minima in the interference pattern if the two slits used in Young's experiment have width ratio 4:9.

Explanation

To find the ratio of intensity of maxima and minima in the interference pattern when the two slits in Young's experiment have a width ratio of 4:9, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Relationship Between Slit Width and Intensity**:
The intensity of light coming out from each slit is directly proportional to the width of the slit. If the widths of the two slits are in the ratio 4:9, we can denote the widths as \( B_1 = 4k \) and \( B_2 = 9k \) for some constant \( k \).

2. **Assigning Intensities**:
