Polarized light filters |
Apparently everyone who uses these Google Groups is absolutely
brilliant, or so they all say.
And so I ask these brilliant minds the following.
If you have two Polarized light filters, one a Vertical filter ( V ),
and the other a Horizontal filter ( H ), and you attempt to send light
through both of these filters, there will be 0% of the light passing
through this two filter combination.
However, if you then place a third Polarized light filter between the
two other filters, and rotate this filter such the the orientation is
at a 45 degree angle ( H / V ), suddenly 25% of the light from the
light source gets through.
What is the explanation of this ?

It doesn't require explanation since you just need to update thinking
on how light looks like.

The explanation is that *every* wave can be expressed as the
superposition of two other waves. There is no such thing as a "pure"
wave that can't have this done to it. It's a feature of waves, and
waves do it whether you like it or not.
Thus, if you *think* you have a "pure" wave oriented at 0 degrees and
you shine it on a filter at 45 degrees, then you find that you've just
discovered the part of that wave that is oriented at 45 degrees and
the part of the wave that is oriented at 135 degrees. It does no good
to say, "But none of it was at 45 degrees! It was at 0 degrees." That
is incorrect. A wavee that is at 0 degrees is half at 45 degrees and
half at 135 degrees.

And so I ask these brilliant minds the following.
Thanks again for the compliment.
I feel really good now.

After the first filter V you have 100%
After the diagonal 45° filter there are 50 % left,
diagonally 45° polarized light.
After the final H filter there are 50% of 50% left,
which equals 25%, H polarized.
When you remove the diagonal filter, zero %
pass through the H filter because the wave and the second
filter are orthogonal
Imagine the filters like a sieve or fine grid made
of narrow parallel slots.

Most people will attribute this to Heisenberg Uncertainty Principle, or if
they dont they probably should.
But then, to what do you attribute HUP ?
Is it enough to invoke HUP here and HUP there without knowing why we have
HUP in the first place ?
The mathematical equivalent of Heisenberg Uncertainty Principle is HUP_2,
the "Harris Uncertainty Principle"
The Harris Uncertainty Principle can be understood as follows.
Consider the number 10 = 2+2+2+2+2
Clearly, the number 10 can be written as a sum or a product.
2*5 = 10 = 2+2+2+2+2
If you had to choose between either one or the other, addition or
multiplication, the distinction is arbitrary.
If polarizers behaved the way that we might naively expect them to, this
would violate the distributive property of multiplication.

You have stated what occurs, but not HOW it occurs.
The polarity of the photons that pass through the first ( H ) filter,
are changed in the long run to a ( V ) polarity.
The question is, HOW !

You did not ask that question in your first post.
HOW does something (anything, everything) work?
HOW does the world work?
WHAT is the truth?
