Stationary waves in the air column inside a pipe of length 50 cm and closed at one end have three nodes and three antinodes. What is the wavelegth ?

Explanation

To find the wavelength of stationary waves in a pipe closed at one end with a length of 50 cm and having three nodes and three antinodes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- A pipe closed at one end supports stationary waves. The closed end is a node (N), and the open end is an antinode (A).
- In this case, we have 3 nodes and 3 antinodes.
