GENERAL KNOWLEDGE

Detailed explanation-1: -Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Detailed explanation-2: -Applications of quantum mechanics include explaining phenomena found in nature as well as developing technologies that rely upon quantum effects, like integrated circuits and lasers. Quantum mechanics is also critically important for understanding how individual atoms are joined by covalent bonds to form molecules.

Detailed explanation-3: -The microscopic domain is the foundation of modern physics, which literally covers the concept of relativity theory and quantum mechanics. Quantum mechanics discusses the universe at the atomic level and covers the concept of the uncertainty principle, charge quantization, and wave-particle duality.

Detailed explanation-4: -Quantum mechanics is a theoretical science that deals with the study of the motions of the microscopic objects that have both observable wave like and particle like properties.
