Michael Weiss: A Trivial Exercise
Here's what ought to be a trivial exercise. Say we have a monochromatic
beam of light, photon density N photons per square meter per second,
angular frequency w. [Pronounce that w as if it was spelled
omega.] Well, this is also a plane electromagnetic wave with
amplitude A and angular frequency w. Ought to be possible
just using dimensional analysis to figure out the relationship of A
to N and vice versa.
Last time I tried that, I didn't get what I expected...
