Wave Types
What type of wave moves the medium up and down while the wave moves forward?
Transverse wave
The highest point of a transverse wave.
Crest
A wave has frequency 2 Hz and wavelength 3 m.
6 m/s
The unit for frequency.
Hertz (Hz)
If wavelength increases and frequency stays the same, velocity will do what?
Increase
What type of wave moves the medium back and forth in the same direction as the wave?
Longitudinal wave
The lowest point of a transverse wave.
Trough
A wave travels 10 m/s and has a frequency of 2 Hz.
What is the wavelength?
5 m
The unit for wavelength.
Meters (m)
If frequency increases and wavelength stays the same, velocity will do what?
Increase
Sound waves are what type of wave?
Longitudinal
The distance from crest to crest or trough to trough.
Wavelength
A wave has frequency 5 Hz and wavelength 2 m.
10 m/s
The unit for wave velocity.
Meters per second (m/s)
If a wave has large amplitude, what does that usually mean about its energy?
More energy

Transverse
The height of a wave from the middle (rest position) to the crest.
Amplitude
A wave travels 12 m/s and its wavelength is 3 m.
4 Hz
If a wave has a frequency of 5 cycles per second, its frequency is 5 ____.
Hertz
Which wave property tells how many waves pass a point each second?
Frequency
