Question

A 800hz tuning fork is vibrating, producing a sound wave in the air.

what is the frequency of the sound wave?

800 hz

what is the speed of the sound wave?


what is the wavelength of the sound wave?

Answer 1

The frequency of the sound wave is 800Hz

The speed of sound in a is about 340m/s.

Velocity = frequency x wavelength

making wavelength the subject formula

wavelength = Velocity/frequency.

wavelength = 340/800

wavelength = 0.425m.
