Suppose you wanted to produce a sound wave with a wavelength of 1m
in room temperature air. What would its frequency be? *

340 Hz

Explanation:

The frequency of a wave is the number of oscillations completed by the wave per second.

For a wave, the relationship between wavelength of the wave and its frequency is given by the wave equation:

where

v is the speed of the wave

f is its frequency

is its wavelength

In this problem, we have a sound wave, with wavelength of

The speed of sound waves at room temperature is

Therefore, using the previous equation, we can find the frequency of the wave:

80cm/s.

24cm/s.

53.3cm/s.
