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...

QUESTION 3 Newton's rings are observed in reflected light in an air wedge between the convex surface of a lens, L, and the plane surface of a glass plate using light of wavelength 0.5 microns. The radius of the 10th ring is found to be 11.93 mm. Find the radius of curvature of the Lens in m.

*Question 266: Thin Film Two pieces of glass are held together in such way that the air space between them forms a very thin wedge. Light of wavelength 469 nm strikes the upper surface perpendicularly and is reflected from the lower surface of the top glass and the upper surface of the bottom glass, thereby producing a series of interference fringes. How much thicker is the air wedge at the sixteenth fringe than it is at the sixth?...

(b) How many wavelengths are contained in the distance 2t,
where t is the thickness of the film? (Do not round your
answer to a whole number.)
(c) What is the phase difference between the wave reflected from
the top of the air-water interface and...

Two rectangular pieces of plane glass are laid one upon the other on a table. A thin strip of paper is placed between them at one edge so that a very thin wedge of air is formed. The plates are illuminated at normal incidence by 550 nm light from a mercury-vapor lamp. Interference fringes are formed, with 20.0 fringes per centimeter. A.) Find the angle of the wedge.
