Interactive LearningWare 27.2 reviews the concepts that are important in this problem. A uniform layer of water (n = 1.33) lies on a glass plate (n = 1.52). Light shines perpendicularly on the layer. Because of constructive interference, the layer looks maximally bright when the wavelength of the light is 434 nm in vacuum and also when it is 651 in vacuum. (a) Obtain the minimum thickness of the film. (b) Assuming that the film has the minimum thickness and that the visible spectrum extends from 380 to 750 nm, determine the visible wavelength (in vacuum) for which the film appears completely dark.

A uniform layer of water (n = 1.33) lies on a glass plate (n = 1.52). Light shines perpendicularly on the layer. Because of constructive interference, the layer looks maximally bright when the wavelength of the light is 438 nm in vacuum and also when it is 657 in vacuum.

A tank of gasoline (n = 1.40) is open to the air (n = 1.00). A thin film of liquid floats on the gasoline and has a refractive index that is between 1.00 and 1.40. Light that has a wavelength of 630 nm (in vacuum) shines perpendicularly down through the air onto this film, and in this light the film looks bright due to constructive interference. The thickness of the film is 272 nm and is the minimum nonzero thickness...
A tank of gasoline (n = 1.40) is open to the air (n = 1.00). A thin film of liquid floats on the gasoline and has a refractive index that is between 1.00 and 1.40. Light that has a wavelength of 612 nm(in vacuum) shines perpendicularly down through the air onto this film, and in this light the film looks bright due to constructive interference.

There is a film of oil (n=1.52) on a wet pavement (n=1.33). the film has a minimum non-zero thickness such that it is dark when viewed in red light (wavelength = 660 nm in vacuum). Assuming that the visible light spectrum extends from 380nm to 750nm, what wavelength in vacuum will you see when you look at the film in broad daylight?
When monochromatic light shines perpendicularly on a soap film (n = 1.33) with air on each side, the second smallest nonzero film thickness for which destructive interference of reflected light is observed is 230 nm. What is the vacuum wavelength of the light in nm?
When monochromatic light shines perpendicularly on a soap film (n = 1.33) with air on each side, the second smallest nonzero film thickness for which destructive interference of reflected light is observed is 354 nm. What is the vacuum wavelength of the light in nm?
4) Blue light (440 nm) shines on water (n-1.33) that has a thin layer of oil (n=1.10) floating on it. What is the minimum thickness of oil that produces constructive interference for this light
A soap film (n = 1.33) is 498 nm thick and lies on a glass plate (n = 1.52). Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels through the air and strikes the film perpendicularly. For which wavelength(s) in this range does destructive interference cause the film to look dark in reflected light? To 3 significant figures
