A sound wave has a frequency of 2700Hz and wavelength of 20cm. What is it’s velocity?

The velocity of the sound wave is 540 meters per second.

Explanation:

The sound is a consequence of mechanic waves, the velocity of a mechanic wave (), in meters per second, is determined by following formula:

(1)

Where:

- Wavelength, in meters.

- Frequency, in hertz.

If we know that and , then the velocity of the sound wave is:

The velocity of the sound wave is 540 meters per second.
