Waves Flashcards
1
Q
Displacement (for oscillations)
A
The distance and direction of an oscillating object from its rest position.
2
Q
Amplitude
A
The maximum displacement of an oscillating object from its rest position
3
Q
Period
A
The time taken for an object to make one complete oscillation
4
Q
Frequency
A
The number of oscillations of a particle per unit time
5
Q
Angular frequency
A
The rate of change of angle expressed in radians per second
6
Q
Phase difference
A
The fraction of an oscillation between two oscillating particles expressed in degrees or radians
7
Q
Path difference
A
The amount by which two waves are out of step with each other
8
Q
Simple harmonic motion
A
Motion of an oscillator whose acceleration is directly proportional to displacement and directed towards the equilibrium position
