Electromagnetic Waves

These waves do not require a medium - they are oscillations in electric and magnetic fields.

 

1. The Transverse Nature of Electromagnetic Waves

EM waves are all around us from long wavelength radio waves to gamma radiation emitted from the rocks beneath your feet. 

 

2. EM Waves: Wavelengths and Frequencies 

You should probably learn this! It is worth having a good idea of the wavelengths of the various parts of the EM Spectrum.
