Find the following :
The wavelengtµ. of a soµnd wave in centimetres if it produces 40 waves in the time taken to travel 80m.

Explanation

To solve the problem of finding the wavelength of a sound wave given that it produces 40 waves while traveling 80 meters, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship**:
The distance traveled by the sound wave can be expressed in terms of the number of waves produced and the wavelength. The total distance traveled (D) is equal to the number of waves (n) multiplied by the wavelength (λ).
\[
D = n \times \lambda
