What is the order of the electromagnetic spectrum |
Radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays |
|
|
What properties do they all have in common |
They are all electromagnetic, travel at the speed of light, travel through a vacuum and are transverse |
|
|
What are the differences |
Frequency, wavelength, energy |
|
|
What do radiowaves have |
The lowest frequency and the longest waves |
|
|
What do gamma rays have |
The highest frequency and the shortest waves |
|
|
What is frequency |
Frequency is a measure of how many waves are produced per second |
|
|
What is the symbol and measure for frequency |
Symbol - f Measure - hertz (hz) |
|
|
What is wavelength |
Wavelength is the distance in which a wave repeats itself |
|
|
What is the symbol and measure for wavelength |
Symbol - lambda Measure - metres |
|
|
What is speed |
Speed is the distance travelled per second |
|
|
What is the symbol and measure for speed |
Symbol - v Measure - m/s |
|
|
What are transverse waves |
Waves that move left to right while the energy moves up and down |
|
|
Give 2 examples of transverse waves |
All electromagnetic waves and water waves |
|
|
What are longitudinal waves |
The wave and the energy move in the same direction |
|
|
Give an example of a longitudinal wave |
Sound waves |
