The vibration frequency of the tuning fork is 440 Hz. What is the sound wavelength from the tuning fork in the air?

Given:

v = 440 Hertz – tuning fork vibration frequency;

c = 330 m / s (meters per second) – the speed of propagation of a sound wave in the air.

It is required to determine l (meter) – the length of the sound wave from the tuning fork.

To determine the length of a sound wave, you must use the following formula:

c = l * v, from here we find that:

l = c / v;

l = 330/440 = 33/44 = 0.75 meters (75 centimeters).

Answer: The sound wavelength is 0.75 meters (75 centimeters).
