What do waves do? |
Transfer energy from one place to another |
|
|
What type of waves don't need a medium to travel through |
Electromagnetic waves |
|
|
What are three examples of mediums |
Rock, water and air |
|
|
Transverse wave: |
Particles move at right angles to the wave |
|
|
Longitudinal waves: |
Particles vibrate backwards and forwards parallel to the direction of wave travel |
|
|
Example of Transverse waves |
All electro-magnetic waves |
|
|
Examples of longitudinal waves |
Sound waves |
|
|
Peak/ crest |
Highest point on a wave |
|
|
Trough |
The lowest point on a wave |
|
|
Wavelength |
|
|
|
Amplitude |
The height of the wave measured from the middle |
|
|
Frequency |
Number of waves produced each second l. Measured in Hz (hertz) |
|
|
Time Period |
Time taken to produce one wave |
|
|
Equation for wave speed using frequency |
Wave Speed = frequency x wavelength |
|
|
Equation for wave speed using distance and time |
Wave speed = distance/ time |
|
|
Time Period Equation |
T = 1/ f |
