Wireless communication Types of waves
Wave are best studied in a tank of water
waves following one direction
If you place a float it will stay on its place.
Although the waves travel from right to left the particles on the surface of the water are simply bobbing up and down
motion
models have been devised to help explain their motion. If you focus on the orange spot, you'll see that it moves up and down.
This movement is at right angles to the direction in which the waves travel so its called a transverse wave
These waves are both transverse but they look different.
The difference is the distance from one peak to the next
This is called the wave lenght and is measure in meters. The top wave has double the wave lenght
Another characteristic of a wave is its frequency.
The number of complete waves which pass a particular point every second
If you change the frequency, the length of the wave changes
You can produce a simple transverse wave by moving spring from side to side.
Another type of wave is given a different name
This time a pulse is sent along the string. Its called a longitudinal wave
The movement of this wave is forward and backwards
Sound waves
Light waves and water waves are both transverse
Sound waves are longitudinal.
There is series of compression waves traveling trough the air
