A displacement-time graph of a wave is a representation of a wave.
A displacement-time graph of a wave shows how the displacement at one point varies as the wave passes
The distance between two wave crests on a displacement-time graph is equal to the period of the wave
The period of a wave, T, is equal to the time of one complete oscillation
Frequency is equal to 1 / period

A displacement-time graph is a picture of a wave.

Interpret and sketch displacement-time graphs of waves that are compared to descriptions of each wave.

Wave medium - the wave medium is the material that a wave can move through.
Displacement - displacement at a point of a wave is the distance that the wave medium is from its rest position.
Period (of a wave) - period (of a wave), T, is the time for a complete wave to pass any point, which is the same as the time to make one complete wave.
Frequency - frequency is the number of waves produced each second. Frequency is measured in Hertz (Hz).
