Question

A longitudinal wave of wavelength 1cm travels in air with a speed
of 330m/sec Calculate the frequency of the wave Can this wave be
heard by a normal human

Pratiksha Pradhan · Accepted Answer

Wavelength= 1cm= 0 01m
Velocity= 330 m/s
Frequency= Velocity/Wavelength= 330/0 01= 33000 Hz
33000>20000
Therefore, frequency of this wave is an ultrasound which can't be
heard by a normal human being

A longitudinal wave of wavelength 1cm travels in air with a speed of 330m/sec. Calculate the frequency of the wave. Can this wave be heard by a normal human.
