Question

Part E Figure 2 of 2 The next graph in (Figure 2) 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) x(m) Taking the speed of sound in air to be 344 m/s, what are the frequency and the wavelength of the sound wave shown in the graph? 10-8 t(s 10-3 Express your answers in, respectively, hertz and meters to three significant figures Separate the two answers with a comma Hints Hz, m

Explanation / Answer

v = 344 m/s

its completes 1 full oscillations in 10^-3 sec.

f = 1/T = 1000 Hz ............Ans

and wavelength = v / f

lambda = 344 / 1000

= 0.344 m .........Ans
