Question

A tuning fork completes one vibration in 1/512 seconds. If the velocity of sound waves is 358.4 m/s in air, find the wavelength of the sound produced.

Answer 1

Hi friend
--------------
Your answer
----------------------

Time taken by the fork to complete one vibration = 1/1512 seconds

Velocity of the sound wave = 358.4 m/s

We know,
-----------------

Frequency (V) = 1/Time period (T)

So,
-----

V = 1/T

So,
------

Frequency = 1512 Hz

Then,
-----------

Wave velocity = Wavelength × Frequency

=> 358.4 = wavelength × 1512

=> Wavelength = 358.4/1512

=> wavelength = 0.237 m
