Anonymous users2024-02-06Quantum mechanics, as a theory of physics, is a branch of physics that studies the laws of motion of microscopic particles in the material world, mainly studying the basic theory of atoms, molecules, condensed matter, as well as the structure and properties of atomic nuclei and elementary particles.
Together with the theory of relativity, it forms the theoretical basis of modern physics. Quantum mechanics is not only one of the basic theories of modern physics, but also widely used in disciplines such as chemistry and many modern technologies.
At the end of the 19th century, it was discovered that the old classical theories could not explain microscopic systems, so through the efforts of physicists, quantum mechanics was created in the early 20th century to explain these phenomena.
Quantum mechanics has fundamentally changed our understanding of the structure of matter and its interactions. With the exception of gravity, which is described by general relativity, all fundamental interactions to date can be described within the framework of quantum mechanics (quantum field theory).

Anonymous users2024-02-04A great description is that "particles have wave-particle duality": when you change the object of study from a classical "particle" to a state or wave function, and add a Bonn statistical interpretation (probability) to convert the relationship of physical quantities into the reciprocal relation of the operator, you move from classical mechanics to quantum mechanics.

Anonymous users2024-02-03Quantum mechanics is a kind of physics theory of microscopic matter, and together with the theory of relativity, it is considered to be the two basic pillars of modern physics, and belongs to many physical theories and sciences, such as atomic physics, solid state physics, nuclear physics, particle physics and other related disciplines, all of which are based on quantum mechanics. The basic principles of quantum mechanics include the concept of quantum states, equations of motion, the concept of Rational Iron, and the corresponding rules and physical principles between observed physical quantities.

Anonymous users2024-02-01In fact, the vernacular is the study of the properties and laws of microscopic objects.
I don't seem to know what exactly is microscopic, not to say that it is invisible or microscopic

The second ** teacher received it. The eigenvalue of the energy of the system is e n=- frace 1, and the wave function can be expressed as the radial wave function of the hydrogen atom (r, theta, phi)=r (r)y ( theta, phi), where e 1= frac$ is the energy of the hydrogen atom in the ground state.
Quantum mechanical.
Hello, happy to answer your <>
Quantum mechanics means quantum mechanics, which is a theory of physics, which is a branch of physics that studies the laws of motion of microscopic particles in the material world, mainly studying atoms, molecules, condensed matter, as well as the basic theory of the structure and properties of atomic nuclei and elementary particles. That's what quantum mechanics means.

**The teacher received that the energy level of the linear potato harmonic oscillator is (n + frac) hbar omega-e, and the wave function is psi n(x)=a ne (x-x n) 2}, where the energy e and the angular frequency omega are determined by the physical parameters of the system.
Kiss [Big Red Sedan Rock], the second ** teacher received it. The eigenvalue of the energy of the system is e n=- frace 1, and the wave function can be expressed as the radial wave function (r, theta, phi)=r (r)y ( theta, phi), where e 1= frac$ is the energy of the hydrogen atom in the ground state.

Expanding:,The third ** teacher received Oh, the first title is that light has wave-particle duality" means that light can exhibit both wave and particle properties. This concept originated from physicists' understanding of the nature of light.
The second title is 1Wave-particle duality: It is known that all matter can exhibit wave and particle properties, including photons, electrons, and proto-microscopic particles.
2.Bohr's model: There are energy levels when the electrons of an atom move around the nucleus, and the electrons can only jump between these energy levels, and the change in the energy of the transition corresponds to the emission and absorption of electromagnetic radiation.
This model is the starting point for modern quantum mechanics research.

The fifth** received Oh, I can't draw it, only text is supported.
Then you type it out line by line.

**The teacher received Oh, the energy eigenvalue is e=(n+ frac) hbar.

Take a look at the above**Oh.
Can't see clearly. Kiss <>
It's very clear.
It is true that infrared photons have less energy than ultraviolet light, but ultraviolet light does not produce a lot of heat. >>>More
On the contrary, the Rat tank was ridiculed by military experts as a 'clay-footed giant', and only two were built, which were attacked and captured by the Soviet army during the test, and never went to the battlefield. At that time, the rat tank could not even solve the problem of how to drive into the battlefield on its own, and it was useless to have powerful firepower and armor protection. Later, a larger E-100 giant rat tank was trial-built, which was also abandoned during the experimental phase. >>>More
