Wave after Wave
A wave transfers energy from one place to another. There are two types of wave.
A transverse wave includes:
Amplitude (A): This is the maximum displacement from the rest position
Wavelength (Lander): This is the distance between 2 adjacent points on a wave that are in phase. (generally in metres).
Frequency (f): THe number of complete cycles per second. 1 cycle per second = 1Hertz
Periods of Oscillation (T): Time taken to complete one wave (seconds).
