Question

a longitudinal wave whose wavelength is 1cm propogates in air at a velocity of 330m/s. calculate the frequency of wave

Answer 1

wavelength= 1 cm = 1*10^-2 m

velocity=330 m/s

wkt

velocity= wavelength*frequency

frequency=velocity/wavelength

f=330/10^-2

f=330 * 10^2

f=33000 Hz

hope this helps
