Question

A person is listening to a tone of 500 Hz sitting from a distance of 450 m from the source of the sound. What is the time interval between succesive compressions from the source?

Answer 1

ΔX = λ = 0.68 m

Step-by-step explanation:

Wave speed is related to wavelength and frequency by the equation

v = λ f

where the speed of sound is 340 m / s

λ = v / f

λ = 340/500

λ = 0.68 m

this is the wavelength, it is the minimum distance for which the wave epitates its movement, which is equal to the distance between two consecutive compressions of the sound

ΔX = λ = 0.68 m
