The frequency of a wave is measured in __________________. 

• inches
• hertz
• meters

• meters per second

As the frequency of a wave increases, the __________________ decreases.

• amplitude
• number of waves

• wavelength
• energy

Increasing the amplitude means you are increasing the _______________ of a wave.

Wave Speed = Wavelength x Frequency

Wave Speed = Distance / Time

The wavelength of a sound wave is 20m. The frequency is 5 Hz. What is the wave speed?

• 4 m/s

• 100 m/s

• 25 m/s

• 15 m/s

When the frequency of a wave increases, what happens to the energy of the wave?

• The energy is not directly affected by the frequency of a wave.

• The energy increases.

• The energy decreases.
