A camera lens with index of refraction greater than 1.30 is coated with a thin transparent film of index of refraction 1.25 to eliminate, by destructive interference, the reflection of light at wavelength λ. the light is incident perpendicularly on the lens. in terms of λ, what minimum film thickness is needed?
