What can be determined from the frequency and wavelength of a wave?

A.) The lifetime of the wave

B.) The velocity of the wave

C.) The height of the wave

D.) The direction of a wave

Is it B ... ?

yeah it's b

Explanation:

The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength ... The speed of sound in a medium is determined by a combination of the medium's rigidity (or compressibility in gases) and its density.
