Matter as a Wave

128 - Matter as a Wave

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer experiment showed that electrons showed interference and were therefore acting as waves.

Gringer. English: A Linear Representation of the Visible Light Spectrum. Colour Ranges Were Taken from “CRC Handbook of Fundamental Spectroscopic Correlation Charts” (see w:Visible Spectrum). Spectral XYZ Locus Coordinates Were Found Here. Every 10nm, the Spectral Locus Point Was Used as the Initial Point in a Search for a Matching sRGB Colour (assuming “Dim” Viewing Condition). The Search Was Carried out by a Binary Search along a Line in JCh Space between the Spectral Point, and a Point with 0.3 * Brightness (J), 0 Chroma (C), and the Same Hue (h) as the Spectral Point. The Search Finished When a Point Was Found That Was in sRGB Space. The CAT02 Matrix Was Modified as Suggested in Brill(2008) to Reduce Yellow-Blue Problems by Replacing the Bottom Row (0.0030, 0.0136, 0.9834) with (0,0,1). An Iterative Smoothing Was Carried out to Eliminate the Largest Jumps in Chroma (greater than 5% Change). Code Used to Generate the Colour Gradient Can Be Found here.Esperanto: Koloroj videblajNederlands: Kleurenspectrum中文（简体）‎: 软件模拟的可见光谱。中文（繁體）‎: 軟件模擬的可見光譜。, August 2008.
