... Single Photon Version: photons sent through double slit one at a time. First experiment by Taylor in 1909. 1. We cannot predict where the photon will arrive on the screen. 2. Unless we place detectors at the slits, which changes the experiment (and the results), we cannot say which slit(s) the photo ...

lesson 5: De Broglie Waves / matter waves
... “One could increase this size by reducing the speed of the bowling ball (recall the wavelength of the de Broglie wave is inversely proportional to the speed of the particle). However, to use a slit of about 10-5 m in width would imply that the bowling ball would have to travel at about 10-29 m/s, wh ...

... We have 2 forms of Schrodinger equation, (a) general, time-dependent solve for Y (x,t), when V(x,t) is given, and (b) TISE, for V=V(x) only. Solve for y(x) when V(x) is given. Solution is a standing wave, ie. Y (x,t)=y(x) e-iw t Wavefunctions are solutions to the Schrodinger wave equation. The w.fun ...

This demonstrates wave-particle duality which states that all matter exhibits both wave and particle properties…. [8]. ...
