1a) A film of oil (n=1.5) is sitting on top of water (n=1.3). If the film of oil is 700nm thick, what

wavelengths of visible light reflect strongly? For reference, visible light has a wavelength in air of

350nm-700nm

1b) What if that same film of oil were sitting on top of glass (n=1.7)?

A pool of water is covered with a film of oil which is 256 nm thick. For what wavelength of visible light (in air) will the reflected light constructively interfere? The index of refraction of the oil is 1.65. Visible light (in air) has wavelengths between 430 nm (blue) and 770 nm (red) in air. Assume that the incident light is normal to the surface of the oil.

A 720 nm thick oil film floats on a plastic plate. White light incident from air strikes the film at normal incidence. What visible wavelengths will be constructively reflected from the film? Take the wavelength of visible light in air to be from 400 nm to 700 nm. The index of refraction of the plate is 1.47 and that of the film is 1.60.

An extremely thin sheet of glass is being inspected at the factory. Illuminated by white light at near-normal incidence, the film-like sheet is 0.397 µm thick and has air on both sides. If the glass has a refractive index of 1.52, what wavelength of visible light (in nm) does it reflect most strongly? (The wavelengths of visible light range from 400 to 700 nm.)

An oil tank ship leaks crude oil (n = 1.2) in the ocean (n = 1.33), making a huge area of oil film. Please calculate: (1) For top view from the airplane above the oil film with thickness of 600 nm, which wavelengths of visible light will have the highest reflection (constructive interference for reflected light)? (2) For bottom view from a diver inside the ocean below the same area, which wavelengths of visible light will have the highest transparency...

The range of light that is visible to human eyes lies between the wavelengths of 400 nm and 700 nm. Suppose a thin film of water (n = 1.33) lies on a surface of glass (n = 1.52). The film has a thickness of 376 nm. What wavelength of visible light will be strongly reflected from the film? (n of air = 1.00) What color is that?

All questions are about the same film with index of refraction 1.3 which is illuminated with colors red of the wavelength 650nm and blue of 390nm wavelength. 1. This film is positioned with upper surface contacting the air and lower surface contacting oil with index of refraction 1.22. What is the minimum thickness of this film which provide strong reflection in magenta color? (magenta color occurs if you are mixing red and blue) 2. What is the next after minimum...

A soap bubble (n 5 1.33) having a wall thickness of 120 nm is floating in air. (a) What is the wavelength of the visible light that is most strongly reflected? (b) Explain how a bubble of different thickness could also strongly reflect light of this same wavelength. (c) Find the two smallest film thicknesses larger than the one given that can produce strongly reflected light of this same wavelength.
