A manufacturer of high quality camera lenses wishes to deposit a special thin film on a lens. The goal is to ensure that, when viewed at normal incidence, the wavelength of 700 nm is suppressed in the reflected light. In other words, this wavelength is missing in the reflection. The film material has a refractive index of 1.4. The glass lens has a refractive index of 1.55. Calculate the minimum thickness required to accomplish this task.
