In the same way that DNA has one strand that cause many different cells, particles have many different shapes. Light has a certain state (remember thatís the word we use to refer to the size and shape and even the speed of a particle), so does sound and electricity. The geometry makes all the difference! If a particle is shaped in a certain way and travels at a certain speed, then it behaves in a certain way. Check out the video below for even more explanation of Law 7!

 

 

Law 7: Energy has different states.
