Document Summary
An interference pattern for light (left) and electrons (right) passing by a sharp. Interference is conclusive evidence for wave-like behavior. An electron microscope makes practical use of the wave nature of electrons. The de broglie wavelength of high-speed electrons is typically thousands of times shorter than the wavelength of visible light, so the electrons are able to distinguish details not apparent with light. In this equation, the thing that waves is a mathematical entity called the wave function, notated as psi or . Probability of finding the particle i am talking about at any position or time. The wave function represents the possibilities that can occur for a system. For a particle confined in a box, the solutions to the shcr dinger wave equation are those standing waves that just fit inside the box. , p, v, ke of a particle confined in a length l. = n any n h p = .
