Young’s Double Slit
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 550 nm, today using monochromatic and coherent light one can calculate wavelength with the following formula: In which, λ is the wavelength of the ...
