That's fine, but that isn't the double slit experiment. And in the
double slit experiment, the interesting behavior is what is *observed*
when there is no detector at either slit.

No, it provides experimental evidence that a particle always exits a
single slit when there is a detector placed at a slit -- that's all.
In order to test whether a particle exits a single slit when there is
no detector at the slit, you're going to have to find a way to do it
without a detector at the slit.

Don't be a doofus. This should be obvious.

But I'm looking at more experimental evidence than your stupid,
restricted "detector experiment" evidence. I'm also including other
experiments like the double slit experiment, including the
configuration when there is no detector at either slit.

Geez, what an ignoramus.

It is obvious if you conclude the particle exits both slits when there
are no detectors at the slit then you are disregarding the
experimental evidence arrived at from the 'Detector Experiment'.

That is what you do when you perform experiments. The arrive at
conclusions based upon the experiment. In the 'Detector Experiment'
the particle is ALWAYS detected exiting a single slit so the 'Detector
Experiment' provides experimental evidence the particle ALWAYS exits a
single slit.

Now, you can conclude the particle exits both slits when you do not
detect it but that is an assumption that is not based upon any
experimental evidence. The experimental evidence is the particle
ALWAYS exits a single slit. The reason why ALL of the experimental
evidence supports the conclusion the particle ALWAYS exits a single
slit because whenever an experiment is executed in order to determine
if the particle exits one slit or both slits the particle is ALWAYS
detected exiting a single slit.

No, we are not. The currently accurately predicts what will be
observed when there are detectors at the slits. Hence that data is not
being disregarded.
It also accurately predicts what will be observed when there are no
detectors at the slits.

No, that would be extrapolating a conclusion beyond what you have data
for. You have data for the class of circumstances in which there is a
detector at the slits. This data does not allow you to conclude what
happens when there is no detector at the slits. You have no data for
that in your "detector experiment". You need a different experiment to
test what happens when there are no detectors at the slits.

Any bonehead would be able to see that?

Are you not even able to see what a bonehead can see?

In experimental science, one learns not to extrapolate findings into
circumstances beyond which you have direct experimental support. You
are guilty of scientific fraud here.

But the experiment is the detectors at the exits. The 'Detector

Anyone who has any clue, except for those in a state of delusional
denial believing in the Copenhagen interpretation of QM understand
placing detectors at the exits to the slits is an experiment. If you
conclude something else occur when you do not perform the experiment
and you have no evidence of that something else then you are assuming
something else occurs which is not supported by the experiment
evidence of the 'Detector Experiment'.

The Copenhagen interpretation of QM is guilty of scientific fraud for
assuming the particle exits both slits when not detected. There is no
evidence the particle exits both slits. All of the experiment evidence
is of the particle ALWAYS exiting a single slit.

you're way off base here. Wavelength is not a property of an assembly
of photons but a property of each individual photon, as per
e = hf
e = hc/lamda
lamda = hc/e

sure it is

since the energy and wavelength are inversely related a direct
measurement of one is an indirect measure of the other. But think of
this, how does a grating spectrometer work? How does it measure the
wavelength of light going through it? Once you've answered that then
ask why would it be any different if there is just one photon of light
going through the spectrometer at a time? The only problem
experimentally is to have a sensitive enough detector.

> Thus, when I measure the wavelength of light, is it a

when a photon is detected it is depositing its energy into a single
atom, bumping electrons into higher orbitals or kicking them out of
the atom. There are other ways light interacts with matter, being
split by a beam splitter or reflecting off a diffraction grating or
some such. These interactions are wave like and I should point out
during these interactions the light is not being detected, it's not
until the light deposits its energy into a detector that it is
detected and this interaction is particle like, one photon at a time.
So when you're measuring the wavelength of light you're still
detecting it as a particle, one photon at a time.

not according to the Copenhagen interpretation of QM.
yeah, I know, it's old hat and you always say "keep up" but I'm not so
sure that keeping up is the best thing to do here.
In spite of how absurd, illogical, counter-intuitive, and just plain
insane the Copenhagen interpretation of QM is, I'm not aware of any
experimental results that contradict it.
In spite of my own prejudices, I like to go with what works.

That's true of all quantum objects, not just photons.
