v=f

Detailed explanation-1: -The speed of a wave can be found using the equation v=f, or velocity = wavelength x frequency.
Detailed explanation-2: -The correct answer is v = f. The wave velocity and the wavelength are related to the wave’s frequency and period by vw=T or vw=f. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ.
Detailed explanation-3: -Wavelength is usually denoted by the Greek letter lambda (); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): = v/f.
Detailed explanation-4: -The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = f, where vw is the speed of sound, f is its frequency, and is its wavelength.
