A thin layer of oil (n = 1.50) floats on water (n = 1.33). Destructive interference is observed for light of wavelength 470 nm. Find the minimum non-zero thickness of the oil film assuming normal incidence.
A thin film of oil (n. =1.50) with varying thickness floats on water (nw = 1.33). When it is illuminated from above by white light, the reflected colors are as shown in the figure below. In air, the wavelength of yellow light is 580 nm. (a) What is the oil's thickness t at point B? (hint: this is the second thinnest region for yellow light]. (b) Estimate (no calculation) the oil's thickness at point A. [hint : use the result...
A very thin oil film (n=1.25) floats on water (n=1.33). What is the thinnest film that produces a strong reflection for green light with a wavelength of 500 nm?
Thin film of Glycerine Due in 12 hours, 9 minutes Light incident normally on a thin film of glycerine which coats a thick glass plate, refractive index 1.55. In the resulting reflections, Completely constructive interference is observed at 420.0 nm and completely destructive interference is seen at 336.0 nm. Take the refractive index of glycerine as 1.28, calculate the thickness of the film. Submit Answer Tries 0/10
A thin film, with a thickness of 277.1 nm and with air on both sides, is illuminated with a beam of white light. The beam is perpendicular to the film and consists of the full range of wavelengths for the visible spectrum. In the light reflected by the film, light with a wavelength of 632.3 nm undergoes fully constructive interference. At what wavelength does the reflected light undergo fully destructive interference? (Hint: You must make a reasonable assumption about the...
Athin layer of oil (n = 1.40) floats on the surface of a puddle of water (n = 1.33). One part of the oil film appears bright greenish-blue, i.e. it strongly reflects light with a wavelength in vacuum of 497 nm. What is the smallest nonzero film thickness of the oil film in this region? 207 nm O 89.0 nm O 124 nm O 249 nm 178 nm
