Question

A bat can hear sound of frequencies up to 120 kHz. Determine the minimum wavelength of sound which it can hear. Speed of sound in air is 330 m/s.

Answer 1

Answer:

2.75 mm

Explanation:

Given

f = 120 kHz = 120000 Hz

v = 330 m/s

WKT

Minimum Wavelength is established at maximum Frequency

And

v = f λ

λ = v/f

λ = 0.00275 m

λ = 2.75 mm
