You want to use a material as a top coating on glass (n3 = 1.60) to suppress the reflection of the green light of about 550 nm. Its refractive index is n; = 1.25. What is the smallest thickness of this layer that will give you the best result at an incidence angle of 30° from the normal? Your answer sheet should reflect the following, sequenced in a coherent manner. A detailed schematic with the relevant information but not overcrowded; the angle of refraction, the phase changeg due to ray 1, the phase change ø due to ray:, the net phase change, the expression of the desired interference according to the problem statement and the smallest thickness t.

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°. What is the index of refraction of the cladding? a) 1.4 b) 1.6 c) 1.2 d) none of these
When light is incident normally on the interface between two transparent optical media, the intensity of the reflected light is given by the expression S1=(n2n1n2+n1)2S1 In this equation, S1 represents the average magnitude of the Poynting vector in the incident light (the incident intensity), S1 is the reflected intensity, and n1 and n2 are the refractive indices of the two media. (a) What fraction of the incident intensity is reflected for 589-nm light normally incident on an interface between air and crown glass? (b) Does it matter in part (a) whether the light is in the air or in the glass as it strikes the interface?
A narrow beam of light containing red (660 nm) and blue (470 nm) wavelengths travels from air through a 1.00-cm-thick flat piece of crown glass and back to air again. The beam strikes at a 30.0incident angle. (a) At what angles do the two colors emerge? (b) By what distance are the red and blue separated when they emerge?
To save money on making military aircraft invisible to radar, an inventor decides to coat them with a nonreflective material having an index of refraction of 1.20, which is between that of air and the surface of the plane. This, he reasons, should be much cheaper than designing Stealth bombers. (a) What thickness should the coating be to inhibit the reflection of 4.00-cm wavelength radar? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
A glass sheet 1.10 μm thick is suspended in air. In reflected light, there are gaps in the visible spectrum at 573 nm and 645.00 nm. Calculate the minimum value of the index of refraction ?n of the glass sheet that produces this effect. ?=
1. a. If a piece of glass (n = 1.5) is coated with a transparent plastic (n = 2.0), will there be aphase shift in either of the beams reflecting off the interfaces (air/plastic and plastic/glass)? Howcan you tell, without doing the experiment, whether or not there will be a phase shift in eitherbeam? Be specific about what rays are reflecting off what materials. b. So what thickness or thicknesses give the maximum reflection? What thickness or thicknesses(hint: it’s thicknesses) give the minimum reflection? Assume that a light of wavelength 500. nmis used, and you may leave the answer in nm. Yes, this is a choice between equations 35.17 and35.18, but your answer to part a should be helpful in deciding which set.
A step-index fiber has an inner cylindrical core surrounded by a cylindrical cladding. The core has an index of refraction (n1 = 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.

The refractive indices for quartz at 762 nm wavelength for left- and right-circularly polarized light are nL= 1.53920 and nR= 1.53914. (a) What thickness of quartz is required to give an optical rotation of 10⁰ at this wavelength? (b) What is the specific rotation of quartz for this wavelength in degree/mm? NOTE, I do not want you to use Chatgpt for the answer. I asked Chatgpt, and every time the answer provided was wrong.
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.
