Find the thinnest oil film of refractive index 1.52 on the surfaceof water for which constructive interference for a red light ofvacuum wavelength 632.8nm takes place by reflection. What is thethinnest (non-zero) thickness when the film appears dark? (Assumethe light beam incident to the film perpendicularly and the indexof refraction for soap water is n=1.33)
????Please show all steps involved and answer all relatedquestions. If not 150% sure of answer please don't respond. Thanksfor your help!
