interference from the edges of opaque liquids was investigated. And in this case, the interference pattern is formed clear, and immediately.
Interference at the boundaries of biological objects, from slices of root crops, such as potatoes, apples and beets, has been investigated.
The classical principle of interference as a superposition of electromagnetic waves confirms its reputation.
But it is not exactly
…Dear reader! In this book, the experiments are presented as if the author performs them in order, in accordance with a certain, previously prepared scheme. This is not true. All life, including science, is a mixture of assumptions, experiments carried out at different times, combined for the convenience of our reading. The experiment described below was carried out one of the first, in the mid-1990s. Even then, my youthful curiosity was tormented by the question of where the waves crossed in antiphase go. Air, water or electromagnetic – in general, it doesn’t matter. So where?
Not finding the answer in various kinds of manuals in physics, the author turned to experience. He was not alone in his doubts. This, perhaps my first article was published. I present the revised version.
Electromagnetic waves in antiphase. For convenience of presentation, only one component of the beam is shown
So friends, let’s imagine that we took two single-color beams from good lasers and crossed them at a negligible angle (see Fig.). In antiphase. What should happen in this case?
The light… will disappear.
Logically, this is how it happens. But physics is above linear logic. Moreover, it is even higher than higher mathematics. Material objects do not at all want to be added, subtracted and multiplied in some way. They are what they are. And with this, as well as with the temper of a capricious wife, given to you forever, in joy and sorrow, you have to put up with.
The measure of truth is a natural experiment. Therefore, having swayed a little, I proceed to physical experiments.
Experience with “black light”
Take a look at the picture, curious reader. Number (3) indicates a source of coherent light, a laser pointer. (4) – diffraction grating. Here the light is split into many coherent rays. If you put a piece of paper in the path of this mixture, we will see a speckle. That is, a set of black and white (or, indeed, red and black) dots, similar to what we see on an unset TV screen. In the black areas, according to textbooks, the crossed beams (1,2) are added in antiphase. And, therefore, they disappear for a while for the world.
What if, in such an invisible state, light completely ceases to interact with gross matter? In particular, with hitherto impenetrable screens? Having passed the prescribed paths without any extinction, the rays go out of each other and appear to the astonished observer as if emerging from the void?!..
…We charge the camera (7) with a film of 400 light sensitivity units. Instead of a lens, we have a tube (6). The obstacle in the path of light is metal foil. We turn on the laser, open the shutter for a few hours. We expect that the paired rays, having overcome the screen in the region of space (5), will disperse inside the tube and illuminate the photographic film. It would be interesting. Something like an X-ray with light in the optical range.
But the miracle did not happen. Photos turned out without flare.
…The beams do not stack in antiphase. One wave with its “top” does not close the “bottom” of another. Where there is darkness, there is simply nothing. Physics textbooks indicate something like this, contradicting themselves, and not revealing the essence of the phenomenon.
Let’s try to formulate the unsaid.
The rays, or what looks like that, are distributed in space by the diffraction grating itself. It is this wonderful set of identical “rods” that decides where the light will be and where the darkness will be.
