Types+Of+Waves

=The types of waves:= Waves are all very basically similar in certain ways, however they are all different within their characteristics such as size, shapes and forms. If these waves are observed they may be categorised so we may understand how waves can be interpreted and understood.

=Transverse waves:= Transverse waves are waves passing through a medium that is moving at an angle of 90° to a given line, plane, or surface that the wave is passing through (perpendicular movement).Say a 10 meter jumping rope was swung up and down by a person this creates a pulse therefore a transverse wave is created. As energy is transmitting to the one side to the other side, the singular coils vibrate shift upwards and downwards as the particles of the medium shift perpendicular, (see transverse wave example).

=Longitudinal waves:= Longitudinal waves are waves that travel through a medium that is displaced and moves side by side and having the same distance continuously between themselves (parallel movement). If a pulse or vibration is presented to one end of a slinky which is stretched out across a 20 meter distance the medium will move parallel in the transportation of the wave meaning individual coils of the medium will be displaced side by side. In this case, the particles of the medium move parallel to the direction that the pulse move.

=Electromagnetic waves Vs Mechanical waves=

Summary
There are different aspects when comparing electromagnetic waves and mechanical waves. The reason why we compare is because of each waves ability to travel through vacuums which are empty spaces where no mediums exist.

Electromagnetic waves
Electromagnetic waves are certain waves in which the energy can be transmitted and transported through a vacuum (E.g. Empty space). For an electromagnetic wave to exist it needs vibration to charge particles. Main types of electromagnetic waves are light. An example may be light waves from the sun being transported through empty space to certain areas. In conclusion electromagnetic waves don't need a medium and are dominantly light waves because they are able to move through air and space.

Mechanical waves
Mechanical waves are certain waves in which the transportation of the wave and energy cannot move through any vacuums (E.g. Empty space). A mechanical wave always requires a medium for the wave to be transported to its destination for example a piece of string hung 5cm in the air which is 40 meters long held up by two metal poles on each end. If a hammer lightly taped one end of the string a pulse will be introduced and a mechanical wave will be created. When the wave is transported and is at the 20 meter line and if a pair of scissors cut where to 30 meter line was the wave will stop at the 30 meter line.
