The ratio of intensities of two waves is 16:9. What is the ratio of amplitudes? If these two waves produce interference, then find the ratio of maximum and minimum intensities.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the relationship between intensity and amplitude
The intensity \( I \) of a wave is directly proportional to the square of its amplitude \( A \). This can be expressed mathematically as:
\[ I \propto A^2 \]
This means that if we have two waves with intensities \( I_1 \) and \( I_2 \) and amplitudes \( A_1 \) and \( A_2 \), we can write:
...
