A glass plate (n = 1.60) is covered with a thin, uniform layer of oil (n = 1.27). A light beam of variable wavelength from air is incident normally on the oil surface. Observation of the reflected beam shows constructive interference at 677 nm. Determine the minimum non-zero thickness of the oil film.

Consider a glass block (n=1.5) that is covered by a
thin transparent film (n=1.25). White light is incident
normal to the film. When viewed in reflected light, fully
destructive interference occurs at 600 nm and fully
constructive interference at 700 nm.

Two identical horizontal sheets of glass have a thin film of air
of thickness t between them. The glass has refractive index 1.40.
The thickness t of the air layer can be varied. Light with
wavelength λ in air is at normal incidence onto the top of the air
film. There is constructive interference between the light
reflected at the top and bottom surfaces of the air film when its
thickness is 700 nm. For the same wavelength of light...

A thin film of alcohol (n=1.36) lies on a flat glass
plate (n=1.51). When monochromatic light, whose wavelength can be
changed, is incident normally, the reflected light is a minimum

A thin layer of transparent oil is placed on top of a
transparent plate. The oil film is then illuminated by white light
shining onto the oil's surface, as shown in the figure above. To an
observer standing right next to the light source and looking
straight down on the oil film, the oil film appears green,
corresponding to a wavelength of 528 nm in air. The oil has an
index of refraction of 1.52.

A thin piece of glass with an index of refraction of
n2 = 1.50 is placed on top of a medium that has an index
of refraction n3 = 2.00, as shown in the figure. A beam
of light traveling in air (n1 = 1.00) shines
perpendicularly down on the glass. The beam contains light of only
two colors, blue light with a certain wavelength and orange light
with a certain wavelength.
