Quantum mechanics
Introduction of quantum mechanics
Once Newtonian classical mechanics was thought as the most valuable part in physics that was the basis of most of the physics theorem and phenomenon. But with the emergence of a few of great limitation in Newtonian classical mechanics, scientists started to think about a new way that can properly explains the unexplained phenomenon of physics.
Exactly, the term "mechanics" concerned with motion. Mechanics is in that term indicates about the study of motion of bodies. Bodies is something objects. The body may be macroscopic or microscopic. The variability of mechanics in physics is depends on the body sizes. The mechanics of small scale bodies are not similar with the mechanics of large scale bodies. The Newtonian classical mechanics are appropriate in all types of large scale bodies. In terms of small scale bodies Newtonian classical mechanics shows it's limitations. Newtonian classical mechanics does not explain most of the physics law concerned with small scale elements behaviour. Just for example, the subatomic particle electrons motion and behaviour can not explain by Newtonian classical mechanics. The large scale elements, such as stars, galaxies, planets or any other visible matters physical laws are explained by Newtonian classical mechanics.
Quantum means a minimum amount of entity with an interaction.
Discrete value and continuous value
The two of the term of mathematics is very important to understand about quantum mechanics. In language, both two term is difficult to define, but very easy to understand with analogy and example. Just think about drop of rain falling from a big sizes cloud. The falling of drops of rain is discrete. It is not continuous.
Another example may give. Just think you dug a small pond near a river. You made a drain if the water flow into empty pond from river.
This flow of water and happens to continuously. On the other hand you are taking water from pond into a drum and carrying it to your house. This kinds of water movement is discrete movement.
Quantum mechanics
Mechanics is concerned with study of motion of bodies. Everything motion surrounding us we may termed as mechanics. Mechanics is nothing but a motion study. But In physics of motion when only concentrated into Newtonian classical mechanics faces a wide limitation In terms of motion of microscopic particles as well as In behavior of speed of light. Newtonian classical mechanics completely fails to explain the behaviour of speed of light.
At first when clerk Maxwell published his most famous theorem which is called Planks Quantum theory of radiation, dramatically established a New modern era In physics. Planks Quantum theory of radiation is called a foundation theory of quantum mechanics.
Quantum mechanics exactly a combination of a set of physics theorem. Planks Quantum theory of radiation is one of the prominent theorem of quantum mechanics.
Planks Quantum theory of radiation
We may everybody familiar with the thermal radiation. Electromagnetic radiation is just a one kind of thermal radiation. The light emits from an hot iron is so a thermal radiation. When any object let to heat enough it emits energy. Though thermal radiation is well known of as the source of radiant light, but the explanation of the relationship of temperature with the frequencies of the radiation were undiscovered until establishment of quantum mechanics. At first clerk Maxwell, established a mathematical model of thermal radiation in 1900 where he said that thermal radiation is equilibrium with a set of harmonic oscillator.
planks established a relationship that is expressed as bellow,
E = nhf
Where, E is denoted for the energy of an oscillator of the frequency f. h is a constant value that is called planks constant.
Let us describe the above relationship, energy of each oscillator is termed as quantum. Each quantum of the each oscillator is proportional to the frequencies of the oscillators.
Photoelectric effect
Light have a significant impact on metallic surface. In 1887, scientist Heinrich Hertz observes an interesting phenomenon of interaction of light energy on the metallic surface. When light energy with specific frequency fall upon a metallic surface, metal surface ejects electron. To discover the amount of energy of ejected electron from metal surface, scientists started to research. 1902, scientist Phillip Leonard found that the energy of the emitted electron is related with the frequency of light.
