SSC MTS EXAM

Detailed explanation-1: -The branch of physics that deals with the study of rigid solid matter are called Solid state physics. It is done through a variety of methods including quantum mechanics, electromagnetism, metallurgy and crystallography and forms the theoretical foundation of materials science as a whole.

Detailed explanation-2: -Traditionally, condensed matter physics is split into “hard” condensed matter physics, which studies quantum properties of matter, and “soft” condensed matter physics which studies those properties of matter for which quantum mechanics plays no role.

Detailed explanation-3: -Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy. It is the largest branch of condensed matter physics.
