Question

A piano string vibrates with a

frequency of 262 Hz. If these sound
waves have a wavelength in the air of
1.30 m, what is the speed of sound?

Answer 1

The speed of sound can be calculated using the formula:

speed of sound = frequency × wavelength

Substituting the given values:

speed of sound = 262 Hz × 1.30 m = 340.6 m/s

Therefore, the speed of sound in air is approximately 340.6 m/s.
