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

1 answer:

5 0

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:
