Question

A bat can hear sound at frequency up to 120 khz. determine the wavelength of sound in air at this frequency. take speed of sound as 344m/s.

Answer 1

Answer:

ans-2.86 m

Explanation:

wavelength=velocity of sound/frequency

Units

velocity=m/s

frequency=Hz

wavelength=m

so,

W=344/120

=2.86 m
