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...

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

The default setting is a thin film of glass(n = 1.5) with air (n
= 1)on both sides.The starting wavelength is 652 nm and the
starting thickness is 544 nm. Use these starting values for this
next set of questions.
1. Is there a phase shift on the front (left) interface? On the
back (right) interface in the simulation?Justify why there is/isn’t
a phase shift at each interface.
2. How does the wavelength in the film (glass) compare to the...
