Question

A sound wave has a frequency of 2500 Hz. What is the distance between crests or compressions? (Assume that the speed of sound is 344 m/s.)

Answer 1

Given:

The frequency of sound is f = 2500 Hz

The speed of sound is v = 344 m/s

Required: The distance between two crests.

Step-by-step explanation:

The distance between two consecutive crests is known as wavelength.

The wavelength can be calculated by the formula

`\lambda=(v)/(f)`

On substituting the values, the wavelength will be

`\begin{gathered} \lambda=(344)/(2500) \\ =0.1376\text{ m} \end{gathered}`

Final Answer: The distance between two crests is 0.1376 m
