Two waves A and B given out from a source are of amplitudes 2 : 3 and frequencies 3:2. Compare their loudness, pitch and quality.

Explanation

To compare the loudness, pitch, and quality of two waves A and B given their amplitudes and frequencies, we can follow these steps:

### Step 1: Understand the relationship between amplitude and loudness
Loudness is directly proportional to the square of the amplitude of the sound wave. This means that if we know the amplitudes of two waves, we can find their loudness using the formula:
\[ \text{Loudness} \propto \text{Amplitude}^2 \]

### Step 2: Calculate the ratio of loudness
Given the amplitudes of waves A and B are in the ratio 2:3, we can denote:
