How is the frequency of a stretched string related to:
Its length?

Explanation

To determine how the frequency of a stretched string is related to its length, we can start by analyzing the formula for the frequency of a vibrating string.

### Step-by-Step Solution:

1. **Understand the Formula**: The frequency \( f \) of a stretched string can be expressed using the formula:
\[ f = \frac{1}{l} \sqrt{\frac{T}{\pi \rho}} \]
