1
Q
Time period
A
time taken for one wavelength or oscillation
2
Q
Phase difference
A
a term used to compare the displacements and relative motions of particles in a wave (usually in degrees or radians)
Particles can be in phase or in antiphase
3
Q
Wave equation
A
velocity = frequency*wavelength
4
Q
Intensity formula
A
intensity = power / area
5
Q
Intensity relationship with amplitude
A
Intensity ∝ amplitude^2
6
Q
Wavefront
A
2D representation of a wave by joining a crest or trough of a wave
