A thin film of polystyrene is used as an anti-reflective 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. What is the least coating thickness that eliminates the reflections at the middle of the visible spectrum ( = 550nm)? Assume that the light is approximately perpendicular to the film surface.
A thin film of polystyrene of refractive index 1.49 is used as a nonreflecting coating for Fabulite (strontium titanate) of refractive index 2.409. What is the minimum thickness of the film required? Assume that the wavelength of the light in air is 550nm .
A thin film of polystyrene is used as an antireflective coating for fabulite (known as the substrate).

What is the thinnest film of a coating with n = 1.38 on glass (n=1.52) for which destructive interference of the red component (640 nm) of an incident white light beam in air can take place by reflection?
Question 9 1 pts A glass (n 1.5) has a thin film coating (n = 2.3). What is the thinnest coating (in nm) that maximizes the intensity of reflected light with wavelength 499 nm (in air)?
1. We want to make a thin film coating we can apply to the outside of a glass window that will cancel (or at least significantly reduce) infrared light (heat) from getting into a house or car during the summer. Assume that the wavelength of this light is 1=2000 nm, the index of refraction of the air is n=1.00, the film is n=1.75 and the glass is 1.55. nm a. What minimum thickness of the film is needed? This film...

Chapter 27, Problem 15 provides some pertinent background information for this problem. A transparent film (n 1.31) is deposited on a glass plate (n-1.52) to form a nonreflective coating. The film has a thickness of 1.00 x 10-7 m, what is the longest possible wavelength (in vacuum) of light for which this film has been designed? Incident light Film Glass plate Units Number the tolerance is +-2%

A transparent film (n=1.3) is deposited on a glass lens (n=1.5) to form a reflective coating. What is the minimum thickness that would maximize reflection of light with a wavelength of 500.0 nm in air? and the answer 96 nm is incorrect
The thickness of plastic film (in mm) on a substrate material is thought to be influenced by the temperatures at which the coating is applied. In particular, higher temperatures are suspected to lead to thinner coatings. To test this, 11 substrates were coated at 125◦F, resulting in a sample mean coating thickness of
