Coating Of Some Thickness N 1 33 Glass N 1 5 Air Index Of Refraction N 1 00 Light Coming In 1 (34.31 KiB) Viewed 79 times
For the antireflective coating shown in the figure, and incoming
light of wavelength 549 nm, how thick should the coating
be to destructively interfere the reflected light off the
front of the glass and the reflected light off the front of the
film? __________ nm thick (Note that we want the coating to be
as thin as possible.)
What is the next-smallest wavelength of light (also in air)
that will have maximal destructive interference? _____ nm
Coating of some thickness, n = 1.33 Glass, n = 1.5 Air, index of refraction n = 1.00 = Light coming in
