There are a couple of things I should probably not talk about. One of them is photons. But no matter what you think about photons you will probably agree that this is not a very good description of electromagnetic radiation. (from comos4kids.com)
Structure of Energy:
All EM energy waves travel at the speed of light when in a vacuum. No matter what their frequency or wavelength, they always move at the same speed. Some properties of waves, such as diffraction and interference, are also seen in EM radiation. Scientists have figured out that there are tiny particles in these waves. The particles have been given the name photons. The photons are specific units or packets, of energy. Sometimes those particles interact with each other and change the way the light originally behaved.
First, structure of energy? That is weird. Also, the paragraph does not talk about energy as much as the weird things that happen when light interacts with matter (at least thats what I guess they are getting at).
So, how would I have worded this differently? Well, what is the goal of this page? It seems sort of ambitious – to explain EM radiation. Why try to explain such complicated things in such a simple manner?
