Question

A sound wave has a speed of 345 m/s and a wavelength of 4.15 meters. what is the frequency of this wave?

a. 83 hertz
b. 67 hertz
c. 125 hertz
d. 145 hertz

Answer 1

a is the correct answer

from the formula of wave length=v/f

therefore f= v/wave length

these implies f= 345/4.15 = 83.1hertz
