Waves Flashcards
1
Q
Define amplitude
A
Maximum displacement
2
Q
Wavelength
A
Distance between adjacent points on a progressive, which are oscillating in phase
3
Q
Define displacement
A
Distance moved from equilibrium of a point in a wave
4
Q
Define period
A
Time taken for one complete oscillation of a particle
5
Q
Define phase difference
A
The fraction of a cycle (measured in degrees or radians) between the oscillations of two particles
6
Q
Define frequency
A
Number of wavelengths passing a point per unit time
7
Q
Define speed of a wave
A
Distance travelled by a wave per unit time
8
Q
Define longitudinal waves
A
Oscillation is parallel to direction of energy transfer
9
Q
Define transverse waves
A
Oscillation is perpendicular to direction of energy transfer
