Two sound waves from two different sources interfere at a point to yield a sound of varying intensity. The intensity level between the maximum and minimum is 20 dB. What is the ratio of the intensities of the individual waves?

Explanation

To solve the problem of finding the ratio of the intensities of two sound waves that interfere, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship Between Intensity and Decibels**:
The intensity level \( L \) in decibels (dB) is given by the formula:
\[
L = 10 \log_{10} \left( \frac{I_{\text{max}}}{I_{\text{min}}} \right)
...
