Answer:
Speed = 80 m/s
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
Speed = 200 * .40
Speed = 80 m/s
Here is your answer
We know that
Velocity = Frequency × Wavelength (all in SI units)
V= 200×0.40
V= 80m/s
