No notes for slide

- 1. Properties of Waves
- 2. What are waves• A means of transferring energy from one place to another.• Two types of wave: – Transverse, (eg light waves, water waves) – Longitudinal, (eg sound waves)
- 3. Transverse Waves• Vibrates or oscillates at right angles to the direction in which the energy is moving.
- 4. Longitudinal Waves• Vibrations or oscillations are along the direction in which the energy is moving
- 5. Describing Waves• Three ways to describe a wave: Amplitude (A) Wavelength (λ) Frequency (f)
- 6. Amplitude• Waves cause particles in a substance to move from their resting position.• The maximum movement of the particles from this position is called the Amplitude (A).
- 7. Wavelength• The distance from a point on one wave and the corresponding point on the next (eg from crest to crest) is called the Wavelength (λ).• Wavelength is measure in metres (m).
- 8. Frequency• The number of waves produced each second, or passing a particular point each second is called the Frequency of the wave (f).• Frequency is measured in Hertz (Hz).
- 9. Wave Period• The time it takes for a source to produce one wave is called the period (T) of the wave.• It can be calculated from the frequency: T= 1 frequency
- 10. The Wave Equation• There is a relationship between the wavelength (λ), the frequency (f) and the wave speed (v): Wave speed = frequency x wavelength v =fxλ v• The wave speed is measured in metres per f X λ second (m/s)
