QUESTION:

b) Given that the speed of sound in air is 330 ms-1, calculate the frequency of a note which sets up a wavelength of 5 cm in air.

Explanation:

Given Data:

Speed = v = 330 m/s

Wavelength = λ = 5 cm = 0.05 m

Required:

Frequency = f = ?

Formula:

v = f λ

Solution:

f = v / λ

f = 330 / 0.05

f = 6600 Hz
