When I take a green laser pointer and aim it at a white paper I get a green
dot and green diffuse reflection on the white wall. When I take the same
green laser pointer and point it at fluorescent orange and/or fluorescent
pink paper, I get a yellow spot on the paper and I still get green diffuse
reflection. I'm guessing that I'm getting some excitation similar to when it
is lit by UV light. But I don't see why I'm getting the green reflection.
Can someone verify if my excitation idea is on track and explain the why I
get the green reflection? It is as simple as the source is green and some
light is absorbed while non-absorbed photons are reflected?
Thanks in advance.
