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?

Cecil,

OK, we are getting somewhere. According to the equation, we know that
interference has the same units as irradiance. Interesting. Does that
mean that interference doesn't work for fields? Are there multiple
definitions for interference?

I am not at all ignorant of what Hecht has written, but I will admit to
being ignorant of the exact choice of words he uses.
