Sketch the pattern below that you would get if you shone light through two finite-width slits separated by three times the width of the slits (assume the light’s wavelength is of order the width of the slits).

Answer #1

let the width of each slit be 'x' and the separation between the two slits is '3x'

when light of wavelength comparable to width of the slit is allowed to pass through them, interference phenomenon will occur.. let the crest of the wave is indicated with black lines and trough of the wave are indicated with pink lines. the superposition of the two waves coming from the two slits will gives alternate maximum and minimum in intensities resulting the interference phenomenon. 3
