Waves have amplitude, wavelength, frequency and speed
- All waves are disturbances that are caused by a vibrating source
- They transfer energy in the direction that the wave travels, but do not transfer matter
- The amplitude is the distance from the rest position to a crest or trough
- Waves with a greater amplitude have more energy
- The wavelength is the length of a full cycle of the wave, e.g. from crest to crest
- Frequency is the number of complete waves passing a certain point oer second. Or the number of waves produced by a source each second
- Frequency is measured in hertz (Hz). 1Hz is 1 wave per second
- The speed is how fast…
