Question

A sound wave has a wavelength of 0.450 meters. If its speed in cold air is 330 meters/second, what is the wave's frequency?

A. 0.890 hertz

B. 100 hertz

C. 230 hertz

D. 733 hertz

Answer 1

Try using this:\[\huge v=f \lambda\]

Answer 2

...where \(v\) is speed, and \(\lambda\) is wavelength ....

Answer 3

@Greg_D ...and f is the frequency...

Answer 4
