Webbwas also not understood till Quantum mechanical theories came in. Magnetoresistance is zero according to Drude since ; not correct in real systems. ... Plasmons can be described in the classical picture as an oscillation of free electron density with respect to the fixed positive ions in a metal. To visualize a plasma oscillation, ... WebbQuantum theory also known as quantum physics or quantum mechanics is the foundational basis for present-day material science. The theory basically explains the nature and behaviour of matter and energy on the atomic level. Generally, classical physics is often used to explain the occurrences at a macroscopic level.
