Question

Taking the speed of sound in air to be 330 m/s, select the correct frequency of a sound wave with a wavelength of 25 cm:

Answer 1

f = v / λ
f = 330m/s / 0.25m
f = 1320 Hz

Answer 2

Given that

Speed of sound in air is 330m/s

Wavelength is 25 cm = 0.25m

We know that

F = velocity / wavelength

f = 330/0.25

f = 1320hz
