Wave Vocabularly Flashcards
1
Q
wave
A
all waves transfer energy not matter
2
Q
longitudinal
A
longitudinal waves are produced when the vibrations are parallel to the direction of energy
3
Q
transverse
A
transverse waves are produced when the vibrations are perpendicular to the direction of energy
4
Q
amplitude
A
the distance from the centre of a wave to the peak or trough
5
Q
frequency
A
the number of vibrations (or waves) per second in Hertz (Hz)
6
Q
wavelength
A
the shortest distance between two parts of a wave that are in phase (doing the same thing)
7
Q
peak
A
the highest point on a transverse wave
8
Q
trough
A
the lowest point on a transverse wave
9
Q
time period (T)
A
the time it takes for one wave to be produced in seconds (s)
10
Q
compression
A
region of high pressure
11
Q
rarefaction
A
region of low pressure
