Question

Distance between two successive compressions in a wave in 2cm. If velocity of wave is 250m/s, find its frequency.

Answer 1

Here, wavelength = 2cm =0.02m
Velocity of wave = 250m/s
Frequency = wave speed / wavelength
= (250/0.02)hz = (25000/2)hz. = 12500hz.

Answer 2

Here ,

wavelength=2cm=0.02m

Velocity of wave=250m/s

frequency=wave speed/wavelength

=(250/0.02)hz

=(25000/2)hz

=12500 hz
