WebThere is a well-known exercise in the basic courses on quantum mechanics: calculate a wavefunction of a 1D system with a rectangular potential barrier in the middle. The results are then interpreted as scattering of a wave on the said barrier: some part of it gets reflected, and some penetrates (probably tunnels ) the barrier and continues on its way.

The electromagnetic field itself is quantized.
WebThe history of quantum mechanics is an important part of the history of modern physics. The term “Quantum Mechanics” was coined by a group of physicists including Max Born, Wolfgang Pauli and Werner Heisenberg in the early 1920s at the University of Göttingen. Both matter and radiation have characteristics of waves and particles at the ...
