Sorry Gene, there are reflections from AR glass because
the index of refraction is in the ballpark of 1.2222.
The non-existence of reflections from a 1.0 to 1.2
transition in the index of refraction is impossible.

Do you see yourself when you look into an AR mirror? That would explain
a lot.

Of course, human eyes cannot respond in 1/2 of a cycle
at light frequencies. If one had an instrument sensitive
enough, one would see that exact reflection during the
first 1/2 cycle. And it never goes away - it just gets
canceled by a complimentary reflection from the "load".

Maybe we need to slow it down to your brain speed. Would
a two second delay in the beginning of the cancellation
process work for you? SGCL is a Signal Generator equipped
with a Circulator and Load resistor. The lines are lossless.
t0 is when the source wave is first incident upon the
impedance discontinuity at '+'.

Rho=0.7143
100w SGCL--50 ohm line--+--1 sec long 300 ohm line--50 ohm load

At t0+1 sec, a 51 watt reflection exists at point '+' and the
forward power on the 300 ohm line is 49 watts. That 51 watt
reflected wave exists for the two seconds it takes the reflected
wave from the load to arrive. That 51 watt reflected wave is
warming up the load resistor in the circulator during that
time.

You say that 51 watt reflection never existed. Good luck
on being able to prove your assertion.

Cecil,

You are just toooo funny.

You gas on about something that you believe happens in 1/2 cycle, and
you want ME to prove something???

Going back to sleep.

1/2 cycle is a real amount of time in which things happen.
Denying it because you cannot see it is ridiculous.
I slowed everything down for you so it takes two seconds
for something to happen. Why are you afraid to discuss it?
