Answer:

150 Hz = Frequency

Step-by-step explanation:

The formula to find the speed of a wave is found by

Speed = Wavelength x Frequency  where the frequency is in HZ and the wavelength is in meters

60 =  .40*Frequency

Divide each side by .4

60/.4 = .4 Frequency /.4

150 Hz = Frequency

Here is your answer

We know that

Velocity = Frequency × Wavelength (all in SI units)

So,

Frequency = Velocity / wavelength

= 60/0.40

= 150 Hz
