Are you so sure? Most physics scientists aren't... They
agree that light sure behaves like a wave, but it also
behaves like a particle.

Well, yes , an "electromagnetic wave quantum" seems the best
way to visualise
(visualize ;) ) it. I guess the Finnish get the same physics
at school as in Holland... :)

Just wondering... does raytracing get any easier to
understand if you think about light as electromagnetic wave
quanta?
