Wave-Particle Duality


The quantum description of matter ascribes a wavelike aspect to particles of matter. In some circumstances, for example in the photoelectric effect, particles behave primarily as if they are mass points. In other circumstances, they display diffraction and interference as if they are waves. The quantum wavelength of a particle is inversely proportional to its mass, and an object's wavelike aspects will be significant whenever its quantum wavelength is larger than its physical size. Therefore, large objects like cars have imperceptible wavelike attributes but subatomic particles, such as neutrons, have significant wavelike aspects. It is more accurate to view the quantum wave aspect as being a wave of information (like a crime wave) or probability than an undulatory quality.
