Question

Explain Quantum theory and Quantum mechanics in brief.​

Answer 1

$\mathfrak{\huge{\green{Answer}}}$

✨Quantum mechanics, including quantum field theory, is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles. Classical physics, the physics existing before quantum mechanics, describes nature at ordinary scale.

✨A theory of matter and energy based on the concept of quanta, especially quantum mechanics.

Answer 2

Hello Friend..❤️❤️

Ans

-----

Quantum theory

------->A theory of matter and energy based on concept of quantum expressively quantum mechanics .

------->Quantum theory is the theoretical basis of modern physics that explains the nature and behaviour of matter and energy on the atomic and sub atomic is the theoretical basis of modern physics that explains the nature and behaviour of matter and energy on the atomic and sub atomic level .

Quantum mechanics.

The branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles incorporating the concept of quantization of energy .
