Question

Difference between quantum physics and quantum mechanics

Answer 1

Quantum physics" is an umbrella term that refers to any physical theory based on the notion of quantizing some quantity, like energy. Quantum physics begins with quantum mechanics, but proceeds into quantum theory of electromagnetism, quantum theory of nuclear forces quantum theories of gravity.

Quantum mechanics also known as quantum physics, is a branch of physics which deals with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behaviour and interactions of energy and matter..............

Answer 2

Answer:

Theory. Planck's constant (h), a physical constant was introduced by German physicist named Max Planck in 1900. The significance of Planck's constant is that 'quanta' (small packets of energy) can be determined by frequency of radiation and Planck's constant
