Question

What is difference between quantum mechanics and quantum theory

Answer 1

Dear student,

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

Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level
