Default Sobral 1919 eclipse involves deflection of star light by theMoons gravity

is the photon supposed to represent one cycle
of periodic radiation, so that
a continuous wave is like a string of photons?

That's an index gradient. Thanks. That's what I said. Idiot.


No, you have been maintaining that after light bending with INCREASING
index of refraction, it will continue to follow the same bending rule
as it travel through DECREASING index of refraction. You are a liar.
shrug

The result from this bending and that
unbending accounts for merely a position shift.


Prove that. Reference please.


All you have to do is to understand Snell’s law. shrug

http://en.wikipedia.org/wiki/Snell%27s_law

Just what part of


that you have trouble understanding?shrug


Yes. Not a thing there about a positional offset of light due to
refraction through a sphere with an index gradient. Not a thing.
Where is the reference that shows the application of a spherical medium
with an index gradient that produces no bending but a positional offset?
Where?


Oh, yes, it does. The law spells definitively how light will bend.
shrug

Are you bull****ting? Do deities bull****?


He never bull****s, He never lies, and He never bluffs. That is
unlike PD who bull****s, lies, and bluffs anyway he can to justify
that Einstein the nitwit, the plagiarist, and the liar is a god.
shrug

Don’t you understand optics? You obviously don’t understand Snell’s
law. You are not fit to teach any physics class.shrug


PD remains unfit to teach physics. PD cannot even understand the
simple Snell’s law. shrug

One thing that is very interesting is that if gravitational lens

For 'gravitational lensing', put 'magnification'; the real expected
(and observed) effect of light change of direction.
I am not discussing the apparent change of position of a star; rather
the FACT that distant objects (galaxies) are MAGNIFIED.
Hint: Parrallel light does not magnify (may dull or brighten image).
My previous diagram should have included (for the brain dead), light
passing
'below' the 'body'.
You make the diagram, and reach the obvious conclusion, which is that
scenario 2
is the ONLY way in which magnification can occur.

Apparently not.
But there are no mediums involved with this scenario; purely vacuum,
light, and gravity.
No interfaces, refractive indexes etc
Just the principle on how a (magnifying) lens works, and the inference
that GR

Other than a galaxy, whether it is the same one or not, can be seen

Quite true. If gravitational lens behave under Snell’s law, there
should be no magnification. Light passing through a gravitational
lens is shifted in position instead. If gravitational lens behave
like GR mathematics, it is no different to Newtonian physics, and this
so-called magnification is expected. This is very ironic, and it is
eluded all self-styled physicists for over 100 years. shrug

Look at the second derivatives of the curve that you have drawn.

no lensing



-------+++--------- second derivative

Your claim is that there is a region near the Sun's edge where a
grazing light beam INCREASES IN SPEED as it approaches the Sun,
which would result in a reversal in curvature.

You are an idiot.

Exactly. Which is why Snell's law doesn't apply here.

Just the principle on how a (magnifying) lens works, and the inference
that GR
is total crap.


And how do you make that inference based on how a glass object
operates on a completely different principle?

Be easy on KW. Light passing around a massive object WOULD obey
the principle of least action, which is the underlying reason why
Snell's law works.

KW just can't think through the consequences, that's all.
