All waves transfer information and energy, create vibrations and do not transfer matter in the direct they're travelling.
Key words:
- Peak; The highest point of a wave.
- Trough; The lowest point of a wave.
- Wave length; The distance measured between a trough and a peak which is measured by meters.
- Amplitude; The maximum displacement of a wave, also measured by meters.
- Frequency; Number of complete waves passing any point per second and it measure in hertz (Hz).
Note:
- Amplitude is not measured from trough to peak!
- A frequency of 3 Hz also means 3 completed vibrations per second.
There are two equations for waves which are for:
Wave equation: Speed = frequency x Wave length
You may also use the method of the distance, speed and time triangle for this, which is if you wanted to find out the frequency, you would divide the speed by the wave length and if you wanted to find the wave length, you would have to divide the speed by the frequency.
