You discover that light that goes through gold leaf is green.
If the ball is replaced by a cylinder, what will be shown on the screen?What if it's replaced by a box?
Quote from: Bored chemist on 16/12/2022 17:21:26So we know that the light is not going through the metal.So, you still don't know it, yet.

Quote from: Bored chemist on 16/12/2022 17:10:55Incidentally, you need to be very careful with the "edges" of transparent objects.The manufacturers generally polish the edges to give something curved (so it isn't dangerously sharp).But a curved bit of glass is a lens and will produce changes of the light beam that you might not have considered.Can you explain how you have allowed for this factor?What kind of changes do I need to consider?

If someone says "Your experiments on diffraction by "edges" of transparent objects will be misleading because you are not paying attention to the fact that the edges are rounded" it's your job to explain how you accounted for that.Please do so.
[The double-slit experiment] has in it the heart of quantum mechanics. In reality, it contains the only mystery. —Richard FeynmanThe Feynman Lectures on Physics, Vol. I: The New Millennium Edition: Mainly Mechanics, Radiation, and Heat (October 4, 2011), Chapter 37 (Quantum Behavior), page 37-2 (An experiment with bullets). Paperback ISBN-13: 978-0465024933 | Online
Most discussions of double-slit experiments with particles refer to Feynman’s quote in his lectures: “We choose to examine a phenomenon which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery.” Feynman went on to add: “We should say right away that you should not try to set up this experiment. This experiment has never been done in just this way. The trouble is that the apparatus would have to be made on an impossibly small scale to show the effects we are interested in. We are doing a “thought experiment”, which we have chosen because it is easy to think about. We know the results that would be obtained because there are many experiments that have been done, in which the scale and the proportions have been chosen to show the effects we shall describe”.https://physicsworld.com/a/the-double-slit-experiment/
Just in case someone hasn't known what my model of light is, or has already forgotten about it. So far, it can be used to explain various experimental results that I've done. One of the most convincing results is that it allows me to design and correctly predict the results of disjointed twin polarizers and conjoined twin polarizers experiments in microwave frequency. Quote from: hamdani yusuf on 23/11/2020 07:29:54Here is another video investigating the effect of twin polarizer.//www.youtube.com/watch?v=HHVs8Y555ekIt shows the effect of double polarizer when they are close to each other but are still separated electrically. The last part shows the polarisation of microwave coming out from the last polarizer.The next video will show the effect of double polarizer when they are close to each other and electrically connected, so stay tuned.Quote from: hamdani yusuf on 24/11/2020 06:43:06And here are videos demonstrating conjoined twin polarizer//www.youtube.com/watch?v=eVVxSrjvS7o//www.youtube.com/watch?v=k4-357xklQUIn the end of the experiment, it's shown that rotating the receiver can make the reading down to 0, which means that the microwave is linearly polarized instead of eliptical or circularly polarized.

It seems that if we can explain the weirdness of the double-slit experiment,

Quote from: hamdani yusuf on 17/12/2022 08:16:22It seems that if we can explain the weirdness of the double-slit experiment,What weirdness? You need two sources to get interference. Simple linguistics: interference occurs between A and B .
Quote from: alancalverd on 16/12/2022 09:19:39We use continuous wave equations to describe propagation, and quantum mechanics to explain microscopic interactions with matter.What does quantum mechanics tell you about a single photon? Does it have a single frequency? Does it have a finite wave number?

I already explained the edge shape effect on diffraction pattern using rounded edges with different radii

You did if you used science.Where did I discover that? I was lucky.I had the chance to discover it in one of the metalwork classrooms when I was at school.You discovered it when I told you about it in this thread.Now you know that it's true, you can see why you must be wrong about light going through the metal to cause the bright dot.
Quote from: hamdani yusuf on 17/12/2022 05:05:58I already explained the edge shape effect on diffraction pattern using rounded edges with different radiiCould you point out where you showed the effects of what would be almost cylindrical lenses in the light path please?Also, please don't list three videos, the first of which starts by saying the opposite of what I asked about.Thanks
Perfectly transparent medium (or negligible opacity) doesn't cause a light beam to diffract. e.g. air.
Perfectly opaque medium (or negligible transparency, or extremely short penetration depth) doesn't cause a light beam to diffract. e.g. total internal reflection of visible light at glass-air interface
Penetration depth of visible light into a steel object is short, but significant compared to the wavelength. It's clearly much smaller than the diameter of an ordinary bearing ball. Thus, no significant light will go through direct hit to the center of the ball.
Optical phonon has been observed independently among different researchers.
My experiment on conjoined twin polarizers shows that electromagnetic wave can propagate longitudinally in electrically conducting medium.
Any diffraction effect involves a light beam hitting an edge of partially transparent object.
Where did I mention cylindrical lens?
What does quantum mechanics tell you about a single photon? Does it have a single frequency? Does it have a finite wave number?
Does it have a finite wave number?
You didn't, and that's the problem.Because there is a lens, and you seem to be ignoring it.Here's a close up diagram of the edge of a glass cube
From the point of view of light traveling up the diagram near the edge of the block, the bit circled in red looks exactly like a small cylindrical lens.And that will give rise to a beam of refracted light superimposed on any diffracted light.As I said, it's tricky to try to account for this.Please show how you did so.
Here's the model I proposed. I'm not really sure if it's new, since it's based on how a dipole antenna work. Can we derive Huygen's principle from equations of antenna? Or can we derive equations of antenna from Huygen's principle?//www.youtube.com/watch?v=tLGQ29kz5NkInvestigation on microwave 37 : blocking mechanism//www.youtube.com/watch?v=Tky8BwMyUWQInvestigation on microwave 38: blocking mechanism explanation//www.youtube.com/watch?v=uja1rmRTLwoInvestigation on microwave 39: Blocking mechanism evidence
