Representing transverse waves
I can interpret and sketch displacement-time graphs of transverse waves.
Representing transverse waves
I can interpret and sketch displacement-time graphs of transverse waves.
Lesson details
Key learning points
- 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
Common misconception
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.
Keywords
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).
