Hi, I've been pondering over the properties of a beam of light and I'm curious if the concentration of photons in eg. a laser beam can be calculated.
To elaborate on this question, let me ask if we can calculate the number of photons in a beam of light x distance long with a given cross section size.
when I think of a beam of light, I get the notion that the photons that make up the beam are not end-to-end. or are they? when I say end-top-end I refer to the similarities of a liquid compared to a gas.
-I'll stop here for now.
Regards-
Tay
