Young’s Double Slit

The experiment named for Thomas Young’s classic proof of the wave theory of light in 1803. While Young’s original experiment used sunlight and calculated the average wavelength to be 550nm, today using monochromatic and coherent light one can calculate wavelength with the following formula: nλ = xd/L   λ is the wavelength of the light…

Introduction to Young’s Double-slit Experiment

[bscolumns class=”one_third”][/bscolumns][bscolumns class=”two_thirds_last_clear”]The double slit experiment, thought to have been first performed by English scientist Thomas Young circa 1800, generally refers to an experiment in which light is allowed to diffract through slits which produces fringes, or wave-like interference patterns on an opposing screen. A similar experiment was performed by Claus Jonsson of the University…
