If two light waves having same frequency have intensity ratio `4:1` and they interfere, the ratio of maximum to minimum intensity in the pattern will be

Explanation

To solve the problem of finding the ratio of maximum to minimum intensity when two light waves with the same frequency interfere and have an intensity ratio of 4:1, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Given Intensities**:
Let the intensities of the two waves be \( I_1 \) and \( I_2 \).
Given the intensity ratio \( \frac{I_1}{I_2} = \frac{4}{1} \), we can express this as:
\[
