Question

Part 2/2 please.The answer to Part 1/2 is 4.5 m

Answer 1

In order to calculate the wave speed, we can use the formula below:

`v=\lambda f`

Where lambda is the wavelength and f is the frequency.

If the wavelength is 4.5 meters and the frequency is 3 Hz, the speed is:

`v=4.5\cdot3=13.5\text{ m/s}`
