Nonreflective Coatings for Camera Lenses Reduce the Loss of Light $\lambda$

question 49

Short Answer

Nonreflective coatings for camera lenses reduce the loss of light at various surfaces of multi-lens systems,as well as preventing internal reflections that might mar the image.Find the minimum thickness of a layer of magnesium fluoride (n = 1.38)on flint glass (n = 1.66)that will cause destructive interference of reflected light of wavelength $\lambda$ = 550 nm,a wavelength which is near the middle of the visual spectrum.
