Two sources with intensity `9` :`4` interfere in a medium. Then find the ratio of maximum to the minimum intensity in the interference pattern.

Explanation

To solve the problem of finding the ratio of maximum to minimum intensity in the interference pattern created by two sources with intensities in the ratio of 9:4, we can follow these steps:

### Step 1: Define the Intensities
Let the intensities of the two sources be:
- \( I_1 = 9 \)
- \( I_2 = 4 \)

### Step 2: Calculate the Maximum Intensity
