Calculate the minimum thickness needed for an anti reflective coating (n=1.38) applied to a glass lens in order to eliminate (a) blue (450 nm), or (h) red (720 nm) reflections for light at normal incidence.
Step 1 of 4 </p>
The film having refractive index of 1.38 is coated on the surface of a glass. Th refractive index of the glass is bigger than the film. This results interference on the surface of a film as in the picture with a path diffreces of the .
Step 2 of 4</p>
The path difference of causes the interference pattern on the surface of the film
with changing thickness d. As in the picture below.
