The fundamental frequency of a closed organ pipe is equal to the first overtone frequency of an open organ pipe. If the length of the open pipe is 60 cm, what is the length closed pipe?

Explanation

To solve the problem, we need to find the length of a closed organ pipe given that its fundamental frequency is equal to the first overtone frequency of an open organ pipe. The length of the open pipe is provided as 60 cm.

### Step-by-Step Solution:

1. **Understand the Frequency Formulas**:
- For a closed organ pipe, the fundamental frequency (\( \mu_0 \)) is given by:
\[
\mu_0 = \frac{V}{4L_{\text{closed}}}
