## Waves - Test 2

What is the period of a periodic wave that has a frequency of 60.hertz?

- 3.0 x 10^-3
- 1.7 x 10^-2s
- 3.3 x 10^2s
- 2.0 x 10^4s

A characteristic common to sound waves and light waves is that they

- are longitudinal
- travel in a vacuum
- are transverse
- transfer energy

What is the wavelength of a 30. -hertz periodic wave moving at 60. meters per second?

- 2.0m
- .50m
- 20.m
- 1800m

Two waves have the same frequency. Which wave characteristic must also be identical for both waves?

- amplitude
- period
- phase
- intensity

The number of water waves passing a given point each second is the waves

- Velocity
- wavelength
- frequency
- amplitude

A wave traveling at 5.0 x 10^4 meters per second has a wave length of 2.5 x 10^1 meters. What is the frequency of the wave?

- 5.0 x 10^-4Hz
- 5.0 x 10^3 Hz
- 2.0 x 10^3 Hz
- 1.25 x 10^6 Hz

As the frequency of a wave increases, the period of that wave

- remains the same
- increases
- decreases
