Applications of quantum mechanics || All Terminology

Quantum Physics :- 
   Quantum physics or Quantum mechanics is the study of matter and energy at it's most fundamental level. A central tenet of quantum mechanics is that energy comes in indivisible packets, commonly known as Quanta. Quanta behave very differently to macroscopic matter. The particles that can behave like waves,  and that waves behave as though they are particles.

An Electromagnetic Wave


Quantum mechanics:- 
     Quantum mechanics is the body of scientific laws that describe the wacky behavior of photons, electrons, and the other particles that make up the whole universe. Quantum mechanics is the branch of Physics that is related to the very small particles. It results in what may appear to be some very strange conclusion about the Physical world.

   Application of quantum mechanics for :- 
 There are very important application of quantum theory including quantum Chemistry, quantum physics, quantum optics, quantum computing, superconducting magnets, light emitting diods(LED), laser, transistor and semiconductor such as microprocessor, medical and research imaging  such as magnetic resonance imaging and electron microscopy.


What are four quantum mechanics ?
    There are total four quantum numbers---
     1. principal quantum number (n),
     2. orbital angular momentum quantum number (l),
     3. Magnetic quantum number (ml),  
      4. Electron spin quantum number (ms).

Wave function:- a wave function in quantum physics is a mathematical description of the quantum state of an isolated quantum system. The wave function is a complex-valued probability amplitude, and the probabilities for the possible results of measurement made on the system can be derived from it. The most common symbol for a wave function are the Greek letters  ψ or Ψ. 


Schrödinger equation, describes
 the behaviour of electron in
an atom


    Schrodinger equation:- it is a linear partial differential equation that describes the wave function or state function of a quantum mechanical system. It is a key result in quantum mechanics. The equation is named after Erwin Schrödinger, who postulated the equation in 1925 and published it in 1926, forming the basis for the work that resulted in his Nobel Prize in Physics in 1933.
