3
New cards
Longitudinal wave
A wave where the particles of the medium vibrate parallel to the direction.
4
New cards
Wavelength
The distance from one point of a wave to another. Eg crest to crest.
5
New cards
Amplitude
The distance from the resting point of the medium to the crest or the trough.
6
New cards
Frequency
How many times a wavelength happens per second, or number of vibrations per second.
7
New cards
Speed
The distance a wave travels in a given amount of time, or the number of meters it travels per second.
8
New cards
Hertz
The unit of frequency. One hertz has a periodic interval of one second.
9
New cards
Pitch
Our ear's perception of the frequency of a sound.
10
