Question

A tuning fork produces a sound of frequency 256 Hz. If the speed of sound in air is 340 m/s, the wavelength of the sound in air is approximately:

Accepted Answer

A. 1.33 m

We have λ = v / ν.
So λ = 340 m/s / 256 Hz ≈ 1.33 m.
**So a 256 Hz sound in air has a wavelength of about 1.33 metres — comparable to a person's height.**

Answer

0.66 m

Answer

256 m

Answer

2.0 m
