The ratio of amplitude of two waves is `2:3`. What is the ration of intensities of these waves?

Explanation

To find the ratio of the intensities of two waves given the ratio of their amplitudes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Ratio of Amplitudes:**
The ratio of the amplitudes of two waves is given as \( A_1 : A_2 = 2 : 3 \).

2. **Express Amplitudes in Terms of a Variable:**
