Question

A sound wave of frequency 640 hz travels boom in 2.5s calculate



a. Speed of sound



b. Wavelength of sound

Answer 1

Velocity = frequency × wavelength

Wavelength = velocity × time or velocity ÷ frequency

And in this case we need know the wavelength so that we can find the velocity

Also we cannot find the wavelength if we don't know the velocity

Meaning there is a problem with the question

Please if there isn't let me know
