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.
Sometimes a nonreflective coating is applied to a lens, such as a camera lens. The coating has an index of refraction between the index of air and the index of the lens. The coating cancels the refle...
Sometimes a nonreflective coating is applied to a lens, such as a camera lens. The coating has an index of refraction between the index of air and the index of the lens. The coating cancels the reflections of one particular wavelength of the incident light. Usually, it cancels green-yellow light (λ 546.0 nm) in the middle of the visible spectrum. (a) Assuming the light is incident perpendicular to the lens surface, what is the minimum thickness of the coating in...

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...

The reflection of light from the thin film of thickness t as
shown in the figure appears violet (400nm) when viewed from above.
This means the two rays reflecting off of the two surfaces
interfere constructively. t is the minimum thickness. The dark grey
material has a higher index of refraction than the light grey with
the white being air. For what minimum thickness relative to t would
it need to be for the film to now appear red (700nm)...

Question 15 5 pts A thin layer of magnesium fluoride (n = 1.38) is applied to the outer surface of a glass (n = 1.52) camera lens as an anti-reflective coating. When viewed from a direction that is nearly perpendicular to the lens in white light, the lens appears slightly green in color, since it only reflects light with a wavelength in vacuum of 540 nm. Based on this information, what is the smallest nonzero thickness of the magnesium fluoride...

Problem 3 [25 pts]: White light, with a uniform intensity across the visible wavelength range of 400 nm to 720 nm, is perpendicularly incident on a glass film, of index of refraction ng = 1.52 and thickness d = 340 nm,, suspended in air. At what wavelength 2 is the light reflected by the film brightest to an observer?
