Waves - Examples
Waves transfer energy from one place to another without transferring matter. Wave motion (the movement of waves) can be shown by the vibrations of a spring or by water waves.

Springs - transverse waves
- Hold one end of a horizontal spring in a fixed position and move the other end of the spring up and down.
- We can observe a wave moving from the end we are holding towards the fixed end of the spring.

Water
- When a wave travels along the surface of water, a cork floating on the surface of the water will only move up and down as the wave passes.
Frequency and Period
All waves have a frequency and a period of oscillation.

Frequency
- Frequency is the number of oscillations (vibrations) per second.
- Frequency = number of oscillations ÷ time
- The frequency is equal to 1 divided by the period.
- Frequency = 1 ÷ period
- Frequency is measured in Hertz (Hz).

Period
- The period of a wave is the time taken to complete one oscillation (vibration).
- It is equal to 1 divided by the frequency.
- Period = 1 ÷ frequency
- The period of a wave is measured in seconds.
