Electromagnetic waves The electromagnetic spectrum

Electromagnetic waves The electromagnetic spectrum

1. Elctromagnetic waves are electric and magnetic disturbances that can be used to transfer energy from a source to an absorber. You use waves from different parts of the elctromagnetic spectrum.

2. Electromagnetic waves do not transfer matter. The energy they transfer depends on the wavelength of the waves.

   • This is why waves of different wavelengths have different effects.
