Chapter 145 Wave 2
Mechanical waves are generated by mechanical vibrations, but why are electromagnetic waves produced by electromagnetic oscillations? We know that for an electric current to occur, it must have an electric charge.
Due to the wave-particle duality of particles, the electrons themselves have radio waves. And we know that radio waves are certainly not part of electromagnetic waves.
In layman's terms, electromagnetic oscillation is produced by periodic changes in charged bodies, magnetic fields, and electric fields.
There is naturally an electric charge in it. The question arises, is electromagnetic wave a single wave, or a composite wave? You think, although electric current can produce a magnetic field, the current is dominant.
Therefore, when electromagnetic waves are formed, the charged body should be stronger. That is, electromagnetic waves are compound waves.
However, if the electromagnetic wave is a composite wave, then it is said that it can be split into two parts. And what are these two parts?
If one part of it is the radio wave corresponding to the electron, and the other part is the magnetic wave of the magnet. And we know that radio waves and magnetic waves are very different, how can they be entangled?
If it's not a radio wave, then what is it? I think a better explanation is that electromagnetic waves are not complex waves but single waves, it is a whole.
It has two parts, though. How to understand? One piece of rope is painted with color, while the other is not.
In this way, the rope becomes two parts. Just as the earth has a rotation and an revolution, the two parts have their own vibrations and common vibrations.
Whereas, the electric current is produced by the movement of a positive charge, but the charge is not an object. Charged bodies are. The waves generated by the charged body are disturbed by the ordered object when they vibrate, resulting in the partial impact of the wave.
As a result, part of the wave becomes an electromagnetic wave. De Broglie waves, also known as matter waves, are the opposite of particle waves.
And there are even people who say that matter waves are probability waves. I thought that the book was there motionless, and suddenly it became a wave.
Or even probability? Movement can cause mass to increase, which can be explained by energy. However, others can also be explained in terms of matter waves.
When the object is at rest, the material waves hardly vibrate. However, the vibrational energy is not zero.
When the object moves, the vibration of the matter wave accelerates. We know that waves are generally valley-based and three-dimensional.
Therefore, when the waves of matter are constantly vibrating, they are constantly absorbing energy and particles from the outside world. These transformations then turn into quality.
So, where does the word probability come from? We know that the position and velocity of the particles cannot be measured at the same time because the particles are moving too fast.
I don't know if you've ever seen an object moving at high speed? Objects could have been seen at slow speeds, but they can't be seen at high speeds.
At this point, we see the image left behind after the object has moved. It's regular exercise.
Without regular movement, it looks disorganized. Probabilistic clouds are used to describe electrons. Actually, this is due to the irregular movement of electrons at high speed.
And this probability is our false feeling, and the truth is that we are seeing images left over from the motion of particles.
Since matter is made up of particles, the waves of matter are necessarily affected by the particles. So, a matter wave is a probability wave.
In addition, it is related to probability density, wave function, Bohr radius, uncertainty principle, probability waves, particle density, Planck's constant, Bragg's law, and de Broglie's hypothesis.
If you have some strong interest in the above concepts, you may wish to search for them.
