- 1Electromagnetic waves can travel through mediums, but they do not require a medium to travelThis means that they can travel through a vacuum!
- 2Electromagnetic waves consist of varying fieldsThese are electric and magnetic fields
- 3The two fields are perpendicular to each other, and to the direction of motionThe magnetic field is on the horizontal plane, and the electric field is on the vertical plane
- 4Both the magnetic and the electric fields have the same frequencyThis is also the frequency of the wave
- 5In a vacuum, electromagnetic waves travel at 2.998 x \(10^8\) \(ms^-1\)This is the speed of light!
- 6The direction of the waves is unaffected by the magnetic and electric fieldsIn general, the waves travel in straight lines
- 7Because thy are transverse, electromagnetic waves can be polrised, and can interfere with each otherThey can also be diffracted.
- 8The electromagnetic spectrum can be broken up into 8 different categories of wavesRadio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays
