Due to an unwanted oil spill, a thin film of oil of refractive index 1.40 floats on water (refractive index 1.33). When sunlight is incident at right angles to this film, the only colors that are absent from the reflected light are blue (458nm) and red (687nm). (a) Draw a diagram showing the reflected rays for either blue or red. (b)Estimate the thickness of the oil film. (c)If the only colors enhanced by reflection were blue and red, what would...

A thin film in air is made by putting a thin layer of acetone (n = 1.25) on a layer of water (n = 1.33). When visible light (400nm – 700 nm) shines normally on the film an observed from above, the bright reflected light looks kind of “purplish” with red light of wavelength 650 nm mixed some blue giving it that appearance and “greenish” light of wavelength 520 nm is completely destroyed. Determine the thickness of the acetone film....

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.

A thin film of soap solution (n = 1.33) has air on either side and is illuminated normally with white light. Interference minima are visible in the reflected light only at wavelengths of 320, 360, and 720 nm in air. 1) What is the minimum thickness of the film? (Express your answer to two significant figures.)

Two identical horizontal sheets of glass have a thin film of air of thickness t between...
Two identical horizontal sheets of glass have a thin film of air of thickness t between them. The glass has refractive index 1.40. The thickness t of the air layer can be varied. Light with wavelength λ in air is at normal incidence onto the top of the air film. There is constructive interference between the light reflected at the top and bottom surfaces of the air film when its thickness is 700 nm. For the same wavelength of light...

Red light with wavelength 600[nm] is incident from air (n = 1.0) onto a thin film of index n = 1.5. The thin film coats a thick slab of material which has index n = 2.0.   1: For what minimum film thickness would the thin film produce no significant overall reflection due to destructive interference? 2: Did the reflections off of those two interfaces have the same phase change (both 0º or both 180º)? Or did the reflections off of...

An anti-glaring uniform thin film of magnesium fluoride (MgF2, index of refraction 1.38) covers a crown glass case of refractive index 1.52. This film has a thickness such that it cancels normally incident light of wavelength 525 nm that strikes the film surface from air. The film is thicker than the minimum thickness to achieve this cancellation. Over time, the MgF2 film wears away at a rate of 2.10 nm per year. What is the minimum number of years before...
