Waves

1

Wave Motion

Waves transfer energy from one place to another when particles, or electric and magnetic fields, vibrate.​

​

  • Transverse waves transfer energy at ninety degrees to the direction of oscillation of the particles

  • Longitudinal waves oscillate in the same direction as energy transfer

2

Wave Period and Frequency

The number of waves passing a point each second is inversely proportional to the time it takes for one oscillation of the wave.

Waves: Example A

To find these values we must take care reading data from the graph.

4

Waves: Example B

Remember that 1 millisecond is 1/1000th of a second.
