a) An oil slick on water is 108 nm thick and illuminated by white light incident perpendicular to its surface. What color does the oil appear (what is the most constructively reflected wavelength, in nanometers), given its index of refraction is 1.41? (Assume the index of refraction of water is 1.33.) wavelength________ nm b)A ruby laser beam is reflected from the surface of a CD onto a wall. The brightest spot is the reflected beam at an angle equal to...

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...

4, Thin films. (a) A film of water (n = 1.33) in air has a thickness t = 320 nm. If it is illuminated with white light at normal incidence, what color will it appear to be in reflected light? (b) Lenses are often coated with thin films of transparent substances such as MgF2 (n - 1.38) to reduce the reflection from the glass surface. How thick t should the coating be to produce a minimum reflection at the center...
