Introduction

Quantum mechanics is a science that studies the behaviour and interaction of light and matter. This presents a description of nature's physical properties at the atomic and subatomic levels. The energy, momentum, angular momentum, and other quantities of a bound system in quantum mechanics are constrained to discrete values, unlike in classical physics. On the scale of atomic and subatomic particles, it explains the behaviour of matter and its interactions with energy.

It tries to explain and describe the properties of molecules and atoms as well as their constituents, such as electrons, protons, neutrons, and even more exotic particles like subatomic particles. Quantum mechanics evolved over time as a way to explain facts that could not be explained by traditional physics. The beginning of the quantum mechanics did not start from a single scientist. Rather, between 1900 and 1930, a group of scientists worked together to provide the groundwork for three innovative notions that eventually acquired recognition and experimental confirmation. Quantum physics describes objects that are neither particles nor waves, but a third category that shares some wave properties and some particle properties.

A key element of the theory is that it can rarely forecast what will happen with confidence, instead relying on probabilities. A probability is calculated mathematically by taking the square of the absolute value of a complex number, which is known as the probability amplitude. This is known as the Born Rule. When you apply the Born rule to these amplitudes, you get a probability density function for the position of the electron when you do an experiment to measure it. This is the most the theory can say; it cannot predict where the electron will be discovered with certainty. One of the consequences of quantum mechanics' mathematical laws is a tradeoff in predictability between distinct measurable quantities.

Thermal radiation is electromagnetic radiation that is emitted from an object's surface as a result of its internal energy. When an object gets sufficiently heated, it emits light at the red end of the spectrum, which is known as red hot. As the temperature rises, the hue shifts from red to yellow, white, and blue, as light is emitted at shorter wavelengths with higher frequencies. When it's cold, a perfect emitter is also a perfect absorber: it absorbs all the light that falls on it and emits none. As a result, a black body is a perfect thermal emitter, and the radiation it emits is known as black-body radiation.

The laser, transistor, electron microscope, and magnetic resonance imaging are all examples of quantum mechanics in action. Macroscopic quantum phenomena such as superfluid helium and superconductors are one type of quantum mechanical application. The discovery of semiconductors led to the development of the diode and transistor, both of which are essential components of modern electronics. Quantum tunnelling is also used to destroy memory cells in flash memory chips found in USB drives. Even in light switches, quantum tunnelling is essential because else the electrons in the electric current would not be able to pass through the potential barrier of an oxide layer.
