A wave that is 2 m long passes by with a frequency of 6 Hz. What is the speed at which this wave travels?

• 12 m/s

• 3 m/s

• 0.5 m/s

• 36 m/s

A wave is traveling at a speed of 500 m/s. If the wave is as long as a soccer field, 100 m, what is the frequency of the wave?

• 500,000 Hz

• 5 Hz

• 0.2 Hz

• 1/5 Hz

• How often a wave goes by.

• How many waves can be completed in one second.

• None of these.

Longitudinal waves require a medium. What is an example of this?

• Sound waves.

• Electric waves.

• Light waves.

• None of these.
