Not sure what you mean by "connected," but a basic principle of quantum mechanics is that its laws must merge with those of classical mechanics if the particle being observed over a certain distance...
The main difference among both is that Classical Mechanics are all rigorously observed under the Laws of Motion of Newton, also known as the Three Laws of Mechanics; whereas the Quantum Mechanics do...
That has been a topic of much debate since the early 1900's. There has been no fully successful tying of the two branches of physics yet but, many proposed theories have made great leaps forward to...
in quantum mechanism the energy of the photon electron vary with the frequency but independent of the intensity of the incident radiation while in classical mechanism the energy of the...
Numerous places:1) photo-electric effect.2) black-body radiation spectrum.3) spectrum of hydrogen emissions.4) interference patterns of electrons through a slit.5) compton scattering.All of the above...
