What types of electromagnetic radiation are there? What happens when radiation hits an object?
Light is one of a family of RADIATIONS called the ELECTROMAGNETIC SPECTRUM.
A beam of electromagnetic radiation ‘packets’ of energy called PHOTONS – each photon carries a tiny quantity of energy of energy, but not all photons have the same amount of energy. The amount of energy carried by a photon depends on the FREQUENCY of the radiation.
ALL types of electromagnetic radiation travel at exactly the same, very high buy finite speed through space (a vacuum) of 300 000km/s.
