Homework Answers
The phenomenon of thin film interference results whenever light reflects off two surfaces separated by distance comparable to its wavelength.Examples of thin film interference are:-
1 Color of soap bubble
2 Color of hummingbird's feathers
3 anti reflection coating on glass
4 color of oil on floating water.

Anti-reflective coatings on lenses use thin-film interference to eliminate the reflection of a particular color
Anti-reflective coatings on lenses use thin-film interference to eliminate the reflection of a particular color. Suppose a glass lens (ng = 1.55) is covered with a thin film (nf = 1.33) to prevent green light (λ = 527 nm) from being reflected. Part (a) Write an expression for the minimum thickness the film can have, t. Part (b) Calculate the minimum thickness, t, in nanometers?

Colors observed in certain fish scales are due to thin film interference. Assume that a fish scale is a translucent wedge having an index of refraction of n=1.2 and it is situated in water, n=1.45. When illuminated with white light, several complete spectra are observed. A. What is the minimum thickness of the scale at the first red spot (l=699nm)? Repeat for the 2nd, 3rd, and 4th spot. We will call these “orders”. B. What is the minimum thickness at...

The brilliant colors observed in certain fish scales are due to thin film interference. Assume that a fish scale is a translucent wedge having an index of refraction of n=1.4 and it is situated in water, n=1.33. When illuminated with white light, several complete spectra are observed. A. What is the minimum thickness of the scale at the first red spot (l=700nm)? Repeat for the 2nd, 3rd, and 4th spot. We will call these “orders”. B. What is the minimum...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...

Which statements about lenses are true? (SELECT ALL THAT APPLY) options: Convex lenses are used to make magnifying glasses. Lenses operate on the principle of refraction. All images formed by lenses are real. Only mirrors make virtual images. The thin lens equation is mathematically the same as the spherical mirror equation.

1.Which of the following statements are true about the six reaction types? (Select all that apply.) The products of some reaction types are predictable. Two ionic compounds react to switch cation and anion partners in a double replacement / precipitation reaction. An acid-base neutralization reaction generates water as one of its products if the base contains the hydroxide ion. A combustion reaction of a hydrocarbon fuel generates water as one of its products. Synthesis is another name for a combination...
