Question

Taking the speed of sound in air to be 344 m/s, what are the frequency f and the wavelength ? of the sound wave shown in the graph?

The next graph shows a sound wave consisting of a sinusoidal displacement of air particles versus time, as recorded at a fixed location. For sinusoidal waves, it is possible to identify a specific frequency (rate of oscillation) and wavelength (distance in space corresponding to one complete cycle). Taking the speed of sound in air to be 344 m/s, what are the frequency f and the wavelength ? of the sound wave shown in the graph?

Explanation / Answer

T=10^-3sec

frequency=1/T= 1/10^-3 = 1000Hz

wavelength=v/frequency =344/1000=.344m

so,

1000Hz, .344m
