A sound wave traveling in water at 144m/s has a wavelength of 0.5m determine the frequency of the wave

Heya!!

For calculate frequency, lets applicate formula:

                                                   Δ   Being   Δ

                                               f = Frequency = ?

                                           v = Velocity = 144 m/s

                                          = Wavelenght = 0,5 m

⇒ Let's replace according the formula:

⇒ Resolving

Result:

The frequency of that wave is 288 Hertz

Good Luck!!

the answer is b ) square root of 5
