Lecture on using the double slit equation to solve problems here: • Solving Problems with Young's Double Slit ...
I give a derivation of Young's double slit formula. The double slit formula is used to find the pattern that the interference of two light waves create when they pass through double slits in a diffraction grating.
Young's double slit formula connects the distance between two slits in a diffraction grating, the distance from the diffraction grating to the wall, the distance between points of maximum constructive interference, and the wavelength of light.
