A good model to see how this blocking works, is by looking at the fact, that atoms can absorb a photon. So if wavelength matches ths properties of the atom, the electrons of a arom take away the energy of a photon, if it comes near enough. So the photon will excite the atoms,and in return, it will be gone. Then the atom might release a new photon later, but in a random direction, or this energy just goes to heat. Also a photon can get reflected.

No, neither monochromaticity, nor even (temporal) coherence are needed. Arago did it with a flame light. What you actually need is spatial coherence at the distances of the order of the diameter of the sphere, so that each wave packet arriving at the sphere is cylindrically symmetric with respect to the axis between the light source and the sphere. For this you can just make sure that your light source is small enough (e.g. emitted through a pinhole) and far enough away from the sphere (this doesn't have to be very far: a few dozens of sphere diameters should suffice if the pinhole is much smaller than the sphere).

Usually stuff like that only works with coherent light that has a consistent wavelength (like a laser) and if the process during which the light is "created" isnt irregular.

well the ball is going down before it hits the ground, and then goes up. So it's reasonable to believe that if it was spinning one direction before it will spin the other after it hits. This is due to the elastic recoil pushing it in the opposite direction it hit the ground with. I should do a video on this:)

@jxrin

@The Action Lab But the elastic recoil should not be strong enough to completely reverse the direction of spin of the ball - I think it may be because the ball flipped upside down during the fall which makes it appear as though it changed the direction of spin, when actually the y axis on the ball was flipped. Edit: Since the ball was dropped by a human we can assume the ball wasn’t dropped on it’s central point of spin. This means the ball won’t go straight up after the bounce, instead, the friction will make it go in another direction which could flip the ball on it’s axis of spin in almost 180 degrees. So in a nutshell, the direction of spin of the ball never changed, as this would require an equal and opposite reaction + some additional energy to account for the loss of energy via air resistance, gravity and other factors which cause loss of momentum. Picture it in your mind, imagine a ball spinning clockwise - when it is upside down, it never changes the direction of spin, it spins in the same direction but upside down, which makes it appear as though the direction of spin was flipped.

@@TheActionLab no it doesn't happen that way....that's considered to violate the newton's second law if so... This is easily observed with the a cricket ball , if you get ro spin the ball it would change its travel direction to a certain angle after it hits the ground or for a faster ball spin you would notice a magnus effect yet ball follows the direction but would never change its spin to opposite direction coz it not only requires exact amount of counter torque but also a bit of extra amount .. For a perfectly elastic collision(** if you theory is correct **) the ball should actually stop spinning but can never get the opposite spin

Each kind of object can cast this type of shadow and make light interfere, it's just that for an ordinary object it's way more difficult to do the math to predict how the Poisson's spot will be. So the ball has the spot, the wire has a Poisson's line and at the ball/wire contact point you have some more complex type of interference.

This isn't a video on quantum mechanics. It's about Fresnel diffraction.

It would be more accurate to say that the light went AROUND the ball, and the interference pattern it created resulted in a bright spot in the middle.

That's not how quantum mechanics works. The light is just a wave of probability and they constructively interfere at the center of the ball.

Wait I thought Quantum mechanics doesn't really come into play here. I thought that this phenomenon can just be explained by considering light as a wave, and the lightest spot in the shadow just being an interference in the diffraction of light around the ball.

so there is a very easy way to experience this yourself without any prep work. go outside and look at a relatively uniform part of the sky(not many clouds) and try to spot "floaters". these are the small things that move around in your vision(microscopic pieces of your eye floating in the fluid in your eye). if you catch one that is round you will see Poisson's spot in the middle of the floater. hopefully I explained it well enough.

I would more describe this as bending the light around the orb rather than going through it as a simpler way of describing it. Of course its more just that the sum of waveforms of the light result in the waveform being focused on the middle at the opposite side of the ball, but i like just saying that it bends around the ball, its easier to understand :) Great video!

Interesting. When light shines on the circular obstacle, Huygens' principle says that every point in the plane of the obstacle acts as a new point source of light. The light coming from points on the circumference of the obstacle and going to the center of the shadow travels exactly the same distance, so all the light passing close by the object arrives at the screen in phase and constructively interferes. This results in a bright spot at the shadow's center, where geometrical optics and particle theories of light predict that there should be no light at all. en.wikipedia.org/wiki/Arago_spot

But you do not need quantum physics for that. Maxwell's laws of electromagnetism will completely describe this as well.

But the reason for this is also quite clear. Light is absorbed by matter that reemits it back with the same frequency (let's forget about inelastic scattering) but in a random direction. That's why the wave front of the point obstacle is spherical.

What would happen if you were to set up a detector between the light source and the sphere? Would the wave function collapse? If so, what would the image being projected on your garage door look like?

It would collapse and the image would be schrodinger's cat trying to capture the dot made by the lazer pointer

I'm a little confused. Light isn't actually going through the ball, it's just that the surface is causing interference on the light waves at the edge of the ball, causing them to scatter, and the waves that randomly converge on the center of the shadow create the point because they accumulate. Right? So that point is actually made up of light that's bent with interference, like a halo around the edge of the ball. Mistitled video!

That's wrong. Photons aren't curving around and coming together behind it, because you could shoot a single photon at a time and get an interference pattern (see double slit experiment). If you treat light as ONLY particles, they might curve around, but they wouldn't shoot STRAIGHT OUT behind the object. And that's what this is about. They behave like waves, but we can measure a single photon and get a position and spin just like any other particle.

This is amazing stuff. Very entertaining. Thanks Mr. Action. Makes my brain gears turn in new ways.

It’s the collective of the potential supper position when you get the light Sorce focal length right the perimeter of the sphere creates a circular pattern the inner pattern is concentrated while the outer bands get dispersed so they are hard to see. In perfect conditions I am sure this will make a bullseye effect.

I remember my 1st grade teacher explaining the concept in conjunction to the planets of our solar system. This was 2004 and one of the planets was directly between the earth and the sun, Venus I think. Because of the distance and how big the sun was we actually didn't have a shadow cast on the earth, but with some welding lenses we could look right at the sun and inside it we saw the other planet.

I also recommend that anyone playing with lasers, carefully read the safe power absorption limits of the retina, and the average & peak power levels of the lasers you play with. Remember that most lasers are not continuous, but have a specific duty cycle, such as 1%, 5%, 20%, or even 50%, and a pulse duration, that must be included in your 'exposure' risk evaluation.

Why rewriting the history? It was Arago, who settled the arguement with that idea and he deserved that the spot was named after him. Btw light hasn't wavelike nature, it's a wave itself and EM field is truly waiving.
