    Just noticed something. Look at the shadow of the wire and notice how there is a bright line right in the center of the wire! That is the same effect happening in a linear fashion. I wish I would have noticed in the video!

      Actually, in this experiment the laser light does NOT shine through the solid ball. Doing the experiment by soldering the ball inside a hole on a steel plate instead of hanging it on a wire can prove that to be the case. Light wave around the ball being able form a bright spot behind the ball due to constructive interference of the light wave around the ball does not mean light actually pass through the steel ball.

      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. The sun emits many wavelengths at very small irregular intervals because the main light source is fusion which is very spontaneous. Might still work tho maybe there is some weird effects canceling each other out...

    I found this weird and I am curious for an explanation

    • @TheActionLab
      @TheActionLab  5 ปีที่แล้ว +928

      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:)

      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

    • @neutronenstern.
      @neutronenstern. ปีที่แล้ว +1

      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.

      ​@@sparkyzcc6178 stuff you learn in school is still vrty fascinating, if you are more interested in details, than in really new stuff. What he does is, he gives some basic information about a topic, that is very very new to most people, and which will then fascinate one. In school however, you learn in physics about stuff you see everyday in a more detailed way. E.g if you learn about centrifugal force, you have all already seen it, and might think its boring. But if you are interested about how one can really describe it, and how and why it works in detail, then school physics is very very interesting.
      You've got to want to know how things work in detail, even if you have seen it a lot in your life, to be fascinated by school physics. But sadly most people arent. They are only interested in completely new stuff, they havent already seen, cause they are easily bored.

      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).

    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.

Since light is a wave, these point sources constructively interfere the maximum at the Center (diffraction) and hence its brightest at Center. So it’s like light goes around it”

      @@Sodium_Slug This isn't quantum physics. It's just Fresnel diffraction and is explained by classical wave theory. Every point at the edge of a circular object casting a shadow is the same distance from the centre of the shadow, so by Huygens-Fresnel principle the wavelets reaching there are in phase and therefore reinforce each other. No QM, just simple geometry.

      Hang all your furniture from support ropes/ strings. Never stub a toe again. And less damage to the shins since they will move. But if it swings back before you move twice the damage.

      Put a bunch of strong magnets in the ground in a circle, all facing a central spot with the same pole. Then put another strong magnet on the leg of the table with the same pole turned to that spot. Now repeat for each leg. You now have a floating table.

    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!
