Gene, you remind me of an ex-friend of mine who when
asked what would happen if he were caught by his wife
in bed with his girlfriend, said, "I would just
deny it."

You said there is no equation for interference.

Hecht in "Optics" provided the equation that you
said didn't exist. I12 is the symbol for interference
between the I1 and I2 waves.

Cecil,

This is getting good. Are you actually claiming that "I" is the symbol
for "interference"? Betcha it ain't. How does Hecht define I1, I2, and I12?

I have plenty of optics books, but I don't have a copy of Hecht. I don't
plan to buy one. I seriously doubt that he says anything very different
from any other author of optics textbooks.
