Question

Difference in quantum physics and quantum mechanics

Answer 1

As most physicist use them, there is no difference. "Quantum mechanics," "quantum physics" and "quantum theory" refer to the same thing. Quantum mechanics encompasses all branches of physics known as "quantum."

Under a few circumstances, the terms could be subtly distinct. For example, quantum physics suggests quantum mechanics as used in physics or by physicists, perhaps in contrast to "quantum chemistry," even though arguably quantum chemistry is a subset of quantum physics. So one would not expect a course entitled "quantum physics" in a chemistry department, even though the content could be almost identical to a physics corse..

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
