1. The size of a vibration or the height of the peaks and troughs of a wave.
2. This transmits vibrations from the outer ear to the small bones in the middle ear.
3. The number of times a wave vibrates in one second.
4. Materials which can prevent sound from travelling.
5. A device which can be used to show sounds as moving waves on a screen. The amplitude and frequency can then be measured.
6. How high or low a sound seems. Fast, high frequency vibrations give h
igh notes. Slow, low frequency vibrations give low notes.
7. Something that makes a sound when it vibrates.
8. The vibrations made by a sound source. Pulses of sound enrgy.
9. Rapid movement backwards and forwards around a fixed point.
10. A regular vibration in a material. Waves carry energy. The bigger the amplitude of the wave, the greater the amount of enrgy.
11. The length of one vibration of a wave.
