In class, we had a demonstration where we turned off the lights and shined a green laser, then blue laser, at a glow in the dark object. The blue electrons stuck and illuminated the object while the green did not have any impact. Why?
Ok. The glow in the dark object dimmed and then the green laser made it glow in the dark again. I know this has something to do with the electron orbital distance but I'm finding it hard to put the pieces together.
