Visible light travels in air, which has an index of refraction of 1.0. It is incident on plastic which is covered by a coating (such that light hits the coating before the plastic). The coating has an index of refraction of 1.6 and is 0.50 microns thick. The ray reflected off the air-coating interface and the ray reflected off the coating-plastic interface experience interference. What frequencies could the light be?

a. The interference is constructive. The plastic used has an index of refraction of 1.7

b. The interference is destructive. The plastic used has an index of refraction of 1.7

c. The interference is constructive. The plastic used has an index of refraction of 1.5

d. The interference is destructive. The plastic used has an index of refraction of 1.5

A transparent oil with index of refraction n = 1.24 spills on the surface of certain crystal (with unknown index of refraction) with a thickness of 0.423 μm. Normally incident red light (wavelength 700 nm in air) produces a maximum of reflection. (a) What can you tell about the index of diffraction of the crystal? (b) Which wavelength in the visible spectrum (400 nm - 700 nm) would also give constructive interference? And destructive? (c) Which index of refraction should...

A material with an index of refraction of 1.11 is used to coat glass. The index of refraction of glass is 1.5. What is the minimum thickness of the coating that will minimize the reflection of light with a wavelength of 5240 ˚A? answer in units of µm. Please explain how you know it is destructive interference, even though both undergo a 180 phase change.

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...
