- Optical flats are flat pieces of glass used to determine the flatness of other optical components. They are placed at an angle above the component as shown in Figure P36.49A, and monochromatic light is incident and observed from above, leading to interference fringes. Figure P36.49C shows the results of one of these tests. What is the approximate difference in the gap thickness between the left and right sides of the optical flat and the component? Is it possible to determine from this figure alone which side has the greater gap thickness (left or right)?

- A step-index fiber has an inner cylindrical core surrounded by a cylindrical cladding. The core has an index of refractionn1 = 1.40. Light of vacuum wavelength 633 nm enters the fiber from air (n0=1.00) at an angle θ0 as shown in the picture below. The incidence angle at the core-cladding interface is the critical angle θc. According to the image given, the critical angle θc for the core-cladding interface is found to be 59°.

In addition, these layers are arranged in patches that are 60 mm across and produce different colors.The color you see is a pointillistic mixture of thin-film interference colors that varies with perspective.

- The quantity nt as shown is called the optical path length corresponding to the geometrical distance t and is analogous to the quantity δ as shown, the path difference. The optical path length is proportional to n because a larger index of refraction shortens the wavelength, so more cycles of a wave fit into a particular geometrical distance. (a) Assume a mixture of corn syrup and water is prepared in a tank, with its index of refraction n increasing uniformly from 1.33 at y = 20.0 cm at the top to 1.90 at y = 0. Write the index of refraction n(y) as a function of y. (b) Compute the optical path length corresponding to the 20.0-cm height of the tank by calculating ∫20cm n(y)dy (c) Suppose a narrow beam of light is directed into the mixture at a nonzero angle with respect to the normal to the surface of the mixture. Qualitatively describe its path.arrow_forwardWhy is the following situation impossible? A piece of transparent material having an index of refraction n = 1.50 is cut into the shape of a wedge as shown. Both the top and bottom surfaces of the wedge are in contactwith air. Monochromatic light of wavelength λ = 632.° nm is normally incident from above, and the wedge is viewed from above. Let h = 1.00 mm represent the height of the wedge and ℓ = 0.500 m its length. A thin-film interference pattern appears in the wedge due to reflection from the topand bottom surfaces. You have been given the task of counting the number of bright fringes that appear in the entire length ℓ of the wedge. You find this task tedious, and your concentration is broken by a noisy distraction after accurately counting 5 000 bright fringes.arrow_forwardThe figure shows the interference pattern that appears on a distant screen when coherent light is incident on a mask with two identical, very narrow slits. Points P and Q are maxima; Point R is a minimum. The wavelength of the light that created the interference pattern is λ=678nm, the two slites are separated by rm d=6 μm, and the distance from the slits to the center of the screen is L=80cm . The difference in path length at a point on the screen is Δs=|s1−s2|, where s1s1 and s2s2 are the distances from each slit to the point. What is ΔsΔs (in nm) at Point P? What is ΔsΔs (in nm) at Point Q? What is ΔsΔs (in nm) at Point R?arrow_forward
