Question

When white light illuminates a thin film normal to the surface, it strongly reflects both blue light (500 nm in air) and red

Answer 1

Answer #1

2nt = (m+ 0.5) since thickness has to be the same, one mvalue 1 larger than the other. (m+0.5) (700) = (m+1.5)(500) foom + 35

A thin film of gasoline floats on a puddle of water at a gas station. Sunlight falls on the film and reflects to your eyes. You see yellow because blue (wavelength 469 nm in vacuum) undergoes destructive interference. The index of refraction for gas is 1.40 and for water is 1.33. (a) What is the wavelength of the blue light inside the gasoline? (b) What is the minimum thickness of the film?

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...

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)...
