Asound wave with a frequency of 400 hz is moving through a solid object. if the wavelength of the sound wave is 8 m, what is the speed of sound traveling through the solid object?

50 m/s

3200 m/s

408 m/s

0.02 m/s

Explanation:

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:

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

answer; (arch); good luck
