The waveparticle duality of light and matter is a fundamental concept in quantum mechanics from "summary" of The World of Physics 2nd Edition by John Avison
The waveparticle duality of light and matter is a fundamental concept in quantum mechanics. This concept suggests that both light and matter can exhibit both wave-like and particle-like properties. This idea challenges the classical understanding of physics, where particles were thought to behave like solid objects with definite positions and velocities. In the early 20th century, experiments such as the double-slit experiment with light and electron diffraction showed that particles could display interference patterns characteristic of waves. This led to the development of quantum theory, which describes the behavior of particles at the smallest scales. According to quantum theory, particles...
