We wish to coat flat glass (n = 1.50) with a transparent material (n = 1.31) so that reflection of light at wavelength 500 nm is eliminated by interference.
(a) What minimum thickness can the coating have to do
this?
(b) What is the next thickness for which destructive interference
would occur?

Suppose we coat a glass window (n = 1.5) with a thin coating in
order to eliminate the reflection for normal incidence radiation,
at a wavelength of 550 nm. Find the reflectance as a function of
wavelength.

A transparent cylindrical tube with radius r = 1.50 cm has a
flat circular bottom and a top that is convex as seen from above,
with radius of curvature of magnitude 2.60 cm. The cylinder is
filled with quinoline, a colorless highly refractive liquid with

A thin film of acetone (n = 1.25) coats a thick glass plate (n =
1.50). White light is incident normal to the film. In the
reflections, fully destructive interference occurs at 480 nm and
fully constructive interference at 560 nm. Calculate the thickness
of the acetone film.

In foxes, there are 2 genes that we
wish to study. For coat color, platinum fur is dominant to
wild-type fur color. For tails, one stripe at the tip of the tail
is dominant to solid tail. Perform a cross between a truebreeding
wild-type coat color and solid tail fox and a truebreeding platinum
coat color, one stripe tail fox. Then take one male and one female
of the F1 generation and cross them together. Give the genotype,
phenotype, and...

A uniform thin film of alcohol (n=1.36) lies on a flat
glass plate (n=1.56). When monochromatic light, whose
wavelength can be changed, is incident normally, the reflected
light is a minimum for ?=515nm and a maximum for
?=644nm.
What is the minimum thickness of the film?
