Making reference to Figure bellow, what is the smallest thickness (t) resulting in destructive interference when viewed from above? Assume monochromatic light of wavelength 750 nm (in vacuum). A) Find the thickness assuming the angle of incidence is perpendicular to the surface. B) Find the thickness if we don't make this assumption and the angle of incidence (to the perpendicular) is 15°.
