Camera lenses (n = 1.45) are often coated with a thin film of magnesium fluoride (n = 1.36). These non-reflective coatings use destructive interference to reduce unwanted reflections. Find the condition for destructive interference in this case, and calculate the minimum thickness required to give destructive interference for light in the middle of the visible spectrum (yellow-green light, λair = 555 nm).
