Photons and Refraction
Name: Christopher S.
Will a single beam of photons refract when entering a
medium of a different density? Thanks for your help.
Yes. A single photon will refract.
A single beam of photons will refract. The simplest example is a laser. A
laser passing through a lens will bend.

Yes, but it is a lot more subtle than you might think. You might look for
a book entitled "Schrdinger's Kittens" for a fascinating tale of the
development of quantum theory -- with no math needed -- and the perplexity
and mystery of the particle / wave duality of light. It truly reveals a
quote attributed to Richard Feynman, "If someone says that they understand
quantum mechanics, they don't understand the problem!"
