Lotie(7) asks How does light travel?

Many thanks for the question Lotie. ‘Light’ is what scientists call a type of Energy. Other common types of Energy (there are quite a few of them) include Heat, Sound and  Electricity….see if you can think of more types of energy.

Let one of my team try to explain WHAT makes something a form of Energy.

The answer is they all can do work. They all can move, in some way. Electricity moves in a wave like motion along the wires that carry it. Light moves by using very, very small particles called Photons. Heat moves by transferring energy from one small particle of a material to another.

Nothing moves faster than a Photon. Sunlight and Light from the Stars is travelling photons.

Thanks again for the question Lotie
