Thin-Film Interference Consider 3 situations in which light of wavelength 600 nm in air reflects perpendicularly from a thin film of thickness 200 nm and an index of refraction of 1.5. In each situation, the film lies between two media with different indices of refraction as shown. Both source and detector are above the film in air. Situation2 Situation.3 Situation1 n 1.4 n 1.4 n=1.5 n 1.3 10. (1.5 points) In which situation or situations will the film appear the...

A thin film of olive oil (index of refraction
noil = 1.46) of thickness d is
floating on the surface of still water (index of refraction
nwater = 1.33). The index of refraction of air
is nair = 1.00.
A red laser of wavelength
λ=600nm=6.00×10−7m is incident on the film of olive oil from above
as shown. The laser reflects at the air-oil and oil-water
interfaces and interferes with itself.
Answer the following questions:
1. What does the thickness d...

A thin film of polystyrene is used as an antireflective coating for fabulite (known as the substrate). The index of refraction of the polystyrene is 1.49, and the index of refraction of the fabulite is 2.409. (Figure 1) Part A What is the minimum thickness of film required? Assume that the wavelength of the light in air is 470 nanometers. Express your answer in nanometers.
A thin film, with a thickness of 277.1 nm and with air on both sides, is illuminated with a beam of white light. The beam is perpendicular to the film and consists of the full range of wavelengths for the visible spectrum. In the light reflected by the film, light with a wavelength of 632.3 nm undergoes fully constructive interference. At what wavelength does the reflected light undergo fully destructive interference? (Hint: You must make a reasonable assumption about the...
