A thin layer of oil (n = 1.51) has been excreted by the microbes living on the surface of your sliced ham (n = 1.84). The light reflecting off of this oil-coated ham has formed a rainbow effect due to constructive inference. Find the condition for constructive interference in this case, and calculate the minimum thickness required to give destructive interference only for light in the middle of the visible spectrum (yellow-green light, air = 554 nm).
