As said, these experiments are a step aside. They were carried out without enthusiasm. But, nevertheless, they gave food for thought.
Experience in interference from screens with different physical and chemical composition
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.
Classic experiment with diffraction
The addition of light waves. This is indicated in physics textbooks. At one angle, the waves add up in antiphase, creating darkness. At a different angle, they reinforce each other. In fact, the question of where the light will be and where the darkness will be is decided earlier. The lattice itself. Which is supposed to have many wonderful properties.
