What is the frequency of a wave of wavelength 34 m? Is it audible to us?
(Take, velocity of sound in air = 340 m/s)
Given that, velocity of sound in air, v = 340 ms-1
Wavelength, A = 34 m
Frequency = v /$\lambda $ = 340/34 = 10 Hz
As 10 Hz of frequency does not lie in the audible range of frequency, so it will be inaudible.
