So the atoms of the red piece of paper I'm holding absorb all light apart from red? but it can't since there are specific energies that can be absorbed, unless the paper has paint on it which is made of a combination of atoms which absorb all the colours apart from red, which sound highly...
Thanks its a lot clearer in my mind
But it still doesn't quite link in with everything else i know
As far as i know atoms are transparent, so how could light be reflected from them? like a leaf, we see it as green because green light is reflected from it, and some gets absorbed and some...
My GUESS is no

Have a look at powering the device, third tab, electricity is the flow of electrons, when the circuit is completed the electrons flow from the cathode to the anode, the electrons are therefore...
I'm confused
So the atoms becaome excited by absorbing energy, like from a hot flame, so this energy makes an electron (or is it all electrons) in the outer shell (or is it all the shells) move to a higher energy level and when the electron(s) return to its(their) ground state, they give off...
