Question

A wave with a frequency of 400 Hz is traveling at a speed of 100 m/s. What is the ​wavelength​? ​


Answer 1

The velocity (speed) of a sound wave (any wave in fact) is related to its frequency and wavelength by the equation . This is easy to remember since it's a distance divided by a time because frequency is the inverse of the period.

Since for sound traveling through the given solid object we have that  and , the speed of sound will be:
