# Waves

HideShow resource information
Transverse waves
In transverse waves, the vibrations are at right angles to the direction of travel. e.g light
1 of 11
Longitudinal waves
In longitudinal waves, the vibrations are along the same direction as the direction of travel. e.g sound
2 of 11
Amplitude
The amplitude of a wave is its maximum disturbance from its undisturbed position
3 of 11
Wavelength
The wavelength of a wave is the distance between a point on one wave and the same point on the next wave. Crest to crest
4 of 11
Frequency
The frequency is the number of complete waves per second.
5 of 11
Wave
Waves are vibrations that carry energy and information without carrying matter
