Waves Flashcards
1
Q
Definition of wave
A
A wave is a disturbance that transfers energy from one point to another without the medium being transferred
2
Q
Transverse waves
A
Waves that travel perpendicular to the direction of the vibration
3
Q
Longitudinal waves
A
Waves that travel parallel to the direction of the vibration
4
Q
Amplitude
A
Maximum displacement from the rest position
In metres
5
Q
Wavelengths
A
Shortest distance between any two points in phase
In metres
6
Q
Period
A
Time taken to produce one complete wave
In seconds
7
Q
Frequency
A
Number of complete waves produced per second
F=1/T

A
V=wavelength/T
m/s
9
Q
Wavefront
A
Imaginary line on a wave that joins all adjacent points that are in phase
10
Q
Crest / trough
A
Highest point/ lowest point of a transverse wave
