Water (n=1.33) in a shallow pan is covered by a thin film of oil that is 450 nm thick and has an index of refraction of 1.45. What visible wavelengths will not be present in the reflected light when the pan is illuminated with white light shining from directly above the pan? Please include a diagram and all relevant equations!

A thin film of soap solution (n = 1.33) has air on either side
and is illuminated normally with white light. Interference minima
are visible in the reflected light only at wavelengths of 480, 520,
and 1040 nm in air.
What is the minimum thickness of the film?

A thin oil slick (no = 1.50) floats on
water(nw = 1.33). When a beam of white light strikes
this film at normal incidence from air, the only enhanced
reflected colors are red (650 nm) and violent (390 nm). From
this information, deduce the minimum thickness t of the oil slick.

a.) A particular patch of a vegetable oil (n=1.30) floating in
water (n=1.33) is 530 nm thick. What is the longest wavelength
which will undergo constructive interference on reflecting from the
surface?
b). For a particular application, you want to apply an
anti-reflective coating to glasses which will minimize reflection
of green light with a wavelength of 550 nm. The index of refraction
is ncoat= 1.30, and it will be applied on glass with index of
refraction of nglass= 1.50....

A thin film of oil (n = 1.4) of thickness 1.4micrometers. is
compressed between two glass slabs (n = 1.5).
White light containing wavelengths from 400 to 700nm (measured in
air) is incident normally on the film.

a) missing (4 of them) and b) enhanced (4 of them)

A thin film of oil (n = 1.28) is located on smooth, wet
pavement. When viewed from a direction perpendicular to the
pavement, the film reflects most strongly red light at 640 nm and
reflects no light at 427 nm. What is the minimum thickness of the
oil film?

A soap film (n = 1.33) is formed in a loop of wire that is
mounted vertically is not exactly uniform in thickness because of
its weight, but wedge-shaped in cross section. When the film is
illuminated with violet light of wavelength 405 nm, one sees that a
distance of 2.20 cm separates two bright fringes that are 4 orders
apart. By how much does the film differ in thickness over this
distance?

mounted vertically is not exactly uniform in thickness because of
its weight, but wedge-shaped in cross section. When the film is
illuminated with green light of wavelength 520 nm, one sees that a
distance of 2.40 cm separates two bright fringes that are 4 orders

A soap film (n=1.33) is 772 nm thick. White light strikes the
film at normal incidence. What visible wavelengths will be
constructively reflected if the film is surrounded by air on both
sides? If there is more than one answer, separate them by a
comma.

An oil film (n = 1.45) floating on the surface of water has
white light incident on it at normal angle of incidence (i.e.
perpendicular to the film). The film is 280 nm thick. For this
problem, you will need to know that the visible spectrum consists
of wavelengths of light from 400 to 700 nm.
