Period |
Time taken for one oscillation |
|
Frequency |
Number of oscillations ocurring in one second |
|
Oscillation |
One complete to and fro movement |
|
Phase |
Is the fraction of an oscillation or cycle that a point on the wave has undergone where one cycle is 360 degrees or 2Pi |
|
Wavelength |
Distance between any two adjacent identical (in phase) points on a wave |
|
Anti-phase |
Points with a phase difference of Pi or 180 degrees are said to be in Anti-Phase |
|
Speed of a wave |
Is the product if its frequency and its wavelength |
|
Amplitude |
Distance between the central or mean position and the position of maximum displaement |
|
Longitudinal waves |
Is a wave in witch the oscillations of the particles is parallel to the direction of energy flow or transfer |
|
Transverse waves |
Is a wave in which the oscillations of the particles is perpendicular to the direction of energy flow or transfer |
|
Coherence |
Constant phase relationship |
|
Superposition |
When waves meet at a point the total displacement at that point is the sum of the individual displacements |
