Speed of a Wave

Select the correct equations.

• Speed = distance / time

• Distance = speed x time

• Distance = speed / time

• Time = distance / speed

• Speed = distance x time

Select the correct equations.

• Speed = frequency / wavelength

• Wavelength = speed / frequency

• Speed = frequency x wavelength

• Frequency = speed x wavelength

• Frequency = speed / wavelength

A water wave is generated by a wave machine in a pool. The wave travels to the end of the pool, is reflected, and travels back to the wave machine. It takes 8.0 seconds for the wave to return to the machine once it has been generated. The wave travels at a speed of 4.5 m/s. How far from the end of the pool is the wave machine?
