Waves

Front 1

Period

Back 1

Time taken for one oscillation

Front 2

Frequency

Back 2

Number of oscillations ocurring in one second

Front 3

Oscillation

Back 3

One complete to and fro movement

Front 4

Phase

Back 4

Is the fraction of an oscillation or cycle that a point on the wave has undergone where one cycle is 360 degrees or 2Pi

Front 5

Wavelength

Back 5

Distance between any two adjacent identical (in phase) points on a wave

Front 6

Anti-phase

Back 6

Points with a phase difference of Pi or 180 degrees are said to be in Anti-Phase

Front 7

Speed of a wave

Back 7

Is the product if its frequency and its wavelength

Front 8

Amplitude

Back 8

Distance between the central or mean position and the position of maximum displaement

Front 9

Longitudinal waves

Back 9

Is a wave in witch the oscillations of the particles is parallel to the direction of energy flow or transfer

Front 10

Transverse waves

Back 10

Is a wave in which the oscillations of the particles is perpendicular to the direction of energy flow or transfer

Front 11

Coherence

Back 11

Constant phase relationship

Front 12

Superposition

Back 12

When waves meet at a point the total displacement at that point is the sum of the individual displacements
