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 is the symbol for irradiance. I1 is the irradiance in
wave 1. I2 is the irradiance in wave 2. I12 is the symbol
for the interference between wave 1 and wave 2, you know
- the symbol that you said didn't exist.

I have plenty of optics books, but I don't have a copy of Hecht.

So during all these months of denying what Hecht has written,
you have been completely ignorant of what Hecht has written?
Why am I not surprised?
