Question

What is the wave speed of a wave that has a frequency of 200 Hz and a wavelength of 0.40 m?

Answer 1

Here is your answer

We know that

Velocity = Frequency × Wavelength (all in SI units)

V= 200×0.40

V= 80m/s

Answer 2

Speed = 80 m/s

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
