Find the following :
Wavelength of a longitudinal wave if the distance between 5th rarefaction and the 6th rarefaction is 25 cm.

Explanation

To find the wavelength of a longitudinal wave given the distance between the 5th rarefaction and the 6th rarefaction, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Wavelength**:
- In a longitudinal wave, the wavelength (λ) is defined as the distance between two consecutive points that are in phase. This can be either from one compression to the next compression or from one rarefaction to the next rarefaction.

2. **Identify the Given Information**:
...
