A wave is a means of transferring energy from one point to another
Waves can be classified as mechanical – where the wave must have a medium to travel through, or electromagnetic, which can travel through a vacuum.
A travelling wave is a wave travelling out from a source, transferring the energy from the source to other places through which it passes.
A travelling wave can be one of two types
Transverse wave = where the direction of vibration is perpendicu...
