Is it able to determine value of IR radiation frequency or not ?
That was a question.

Current way of spaced quoting by GoogleGroups is disaster, if combined
with no quoting by some GG users.
A radar pulse of known frequency can be reflected off an object at a known distance to determine the EM speed in air. Alternatively, knowing EM speed, a radar signal can be used to determine the distance of an object.
A radar pulse is NOT one single photon.

You are a genius at saying what things are not, Wilson.
Pity you can never say what they are.
Still, you can't help being a totally ignorant clueless idiot with a big mouth.

LOL.....so you agree the wavelength of water wave is not changed....right.

The incoming light becomes a new light source in the observer's frame.
The new wavelength is for that new light source. What this mean is that the observed ferequency shift is due to the arrival of light wwave is changed.

Your failure to understand nature is of concern of mine.

SO WHERE ARE THE PHOTONS, YOU POMMIE SMARTARSE?
======================================================
Didn't you see the YouTube video?
Here it is again:
http://www.youtube.com/watch?v=wOtAFgDSVGg There is only one way that bulb will light up -- there is an electric
current in it.
The only "thing" to make that current is... oh wait... the totally ignorant
clueless
idiot said "no" when I asked it about a magnetic loop, so it must be your
well-
defined h-aether jumping up and down, you fucking shit-headed clueless
cantankerous ozzie bastard.
"Radar pulse" my arse, you have absolutely no idea what you are babbling
about,
you bird-brained chicken farmer.

You still haven't mentioned any photons...
====================================================
Saying "photon" to a chicken farmer is like saying "single malt" to an ozzie
wino who says what things are not -- it is NOT fermented grape juice and
you wouldn't appreciate it anyway.

Don't you even know the principle behind radar positioning?
=====================================================
Phased arrays are diffraction gratings running in reverse gear.
Take the magnetron out of a cheap microwave oven and measure
the speed of microwaves, Wilson. Oops, I just said "MAGNETron"
to a chicken farmer who measures intelligence by the bird brain.

Mad bull is rampaging again...Lock your doors and keep your children inside!
================================================================
Abuse is chicken farmer Wilson's standard reply to things he knows nothing
about and refuses to listen when they are explained to him.
Don't you even know the principle of diffraction, and isn't it past your bedtime?

You wanted to know what a photon looks like, that's the best you'll find, chicken farmer.
This symbol
http://upload.wikimedia.org/math/c/2/1/c21b388a48eea039c6761e4bac9e5b... is for the closed loop integral
"Similar to the integral, but used to denote a single integration over a closed curve or loop. It is sometimes used in physics texts involving equations regarding Gauss's Law, and while these formulas involve a closed surface integral, the representations describe only the first integration of the volume over the enclosing surface."
You wouldn't have heard of Gauss's Law, bird brain.
Everybody knows single biological cells are tiny like photons, so birds eggs can't be single cells... but they are and photons can be huge too.
Learn some physics, you wanker. The shape of a photon is a magnetic torus created from an electrical spark.

A chemical reaction such as 2H2 + O2 => 2 (H2O) emits 2 photons, the electron shells of each molecule gets rearranged to produce a new molecule, in this case hydrogen and oxygen, normally gases at STP turn to steam which condenses to liquid at STP. You see it as a flame.
But that only tells you what a flame is, it doesn't say what a photon is. The rods and cones of your eye react like a radio antenna does to a magnetic loop... oops, I just said a bad word to a chicken farmer, the dumb cretin will call me a raging mad bull and an idiot now, the stupid moron is going to change my .sig for trying to explain what a photon is to a raw egg who still thinks a photon is a headless crocodile made of lucky white heather.
In our next exciting episode a train of photons make a wave, but the chicken farmer needs three days of name-calling to get over the excitement of learning something it didn't know before.

That's my point....the wavelength of water waves is not changed.
So that means that the speed of arrival of water waves is increased.

No the wavelength is not changed.....the incoming light becomes a new light source in the observer's frame and the grating defines a
new eavelength for this new light source. The speed of incoming light is calculated as follows:
c'=c(lambda_i/Lambda_s)
Lambda_i = wavelength of incoming light.
Lambda_s = wavelength of source.
