Wave – particle - duality<br />
So, everything is both a particle and a wave --<br />
disturbing!??<br />
“Solution”: Bohr’s Principle of Complementarity:<br />
• It is not possible to describe physical<br />
observables simultaneously in terms of both<br />
particles and waves<br />
• Physical observables:<br />
o quantities that can be experimentally measured. (e.g.<br />
position, velocity, momentum, and energy..)<br />
o in any given instance we must use either the particle<br />
description or the wave description<br />
• When we’re trying to measure particle<br />
properties, things behave like particles; when<br />
we’re not, they behave like waves.<br />
