#Light is a form of energy and travels as electro-magnetic radiation. There are other radiations apart from light that travel as electro-magnetic radiation.

#It is possible to look at light and other electro magnetic radiation as a wave or as a particle known as the photon.

#The different types of photons are seen by us as different colours.
#The different types of photons are seen by us as different colours.
#There are some kinds of photons that we cannot see – for example heat radiation, X rays, infra-red and ultra-violet rays. We say that light travels as a wave and different coloured lights have different wave-length associated with them.
