Question

quantum physics.....................

Answer 1

$\huge\bold\red{ANSWER}$Quantum mechanics, including quantum field theory, is a fundamental theory in physics describing the properties of nature. Classical physics, the description of physics that existed before the formulation of the theory of relativity and of quantum mechanics, describes many aspects of nature at ordinary scale.$\huge{\fbox{\fbox{\bigstar{\bold{\red{Happi\: Holi }}}}}}$

Answer 2

hi mate,

Answer:

quantum physics, quantum theory, the wave mechanical model and matrix mechanics), including quantum field theory, is a fundamental theory in physics describing the properties of nature on an atomic scale.

Quantum Mechanics or QM, describes how the Universe works at the level smaller than atoms. It is also called "quantum physics" or "quantum theory". ... A quantum of energy is a specific amount of energy, and Quantum Mechanics describes how that energy moves and interacts at the sub-atomic level.

The new theory ignored the fact that electrons are particles and treated them as waves. By 1926 physicists had developed the laws of quantum mechanics, also called wave mechanics, to explain atomic and subatomic phenomena. ... When X-rays are scattered, their momentum is partially transferred to the electrons.

i hope it helps you.
