Question

Numerical problems:

A Sound wave travels at a speed of 344 ms^-1. If the wavelength is 1.5 cm, what is the frequency of the Wave? Will it be audible?

Answer 1

Velocity of sound , v = 344ms^-1
The wavelength of sound. λ = 1.5cm

Frequency of the sound υ = `"Velocity"/"wavelength " = (344"ms"^-1)/ (1.5"cm")`

υ = `(344"ms"^-1)/ (0.0015"m")`= 22933 Hz.

Audible frequency range = 20 – 20000Hz
So frequency 2,29,333 is not audible.
