In the model below there are ten atoms but they are of different kinds.
The purple ones are the same kind as the ones you've already seen; the
green ones are different. Run the model, heat it up to get the atoms
excited, and see if you can figure out which photons are emitted by which
types of atoms.

Can an atom ever absorb a photon? Yes, if it has just the right frequency!
The photons that an atom emits are right frequency to be absorbed by
another atom of the same kind. Run the model again and see if you can
observe a photon being absorbed by an atom. When you do, stop the model,
rewind, take a snapshot just before and just after the absorption of the
photon, and paste them below.

 The picture on the left shows an infrared photon. (You can tell it's
infrared because it's black, meaning it's invisible, and it has very few
wiggles, meaning it's low frequency.) Run the model until you see a photon
like this, then stop the model and run it back and forth frame by frame to
figure out which type of atom emits this type of photon. Write your answer
below.
