SSC MTS EXAM

Detailed explanation-1: -The field of particle physics, also known as “high-energy physics", is concerned with the properties of submicroscopic particles much smaller than atoms, including the elementary particles from which all other units of matter are constructed.

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: -quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents-electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
