- For the next two questions, as seen in the image below, two materials A (na = 1.25) and B ( 1.75) are stacked (ray angles for illustration only). A B 1. Monochromatic light hits A at an angle theta, -30° from the normal. What is the angle of refraction of light that gets to come out from B? A. None (total internal reflection occurs at B) B. 60° C. 30° D. 15° 2. Suppose we want to induce the total internal reflection of light in this system by changing either material A, B or adding another material below material B. Which of the following changes would induce total internal reflection? A. Adding a layer of material A below material B. B. Replacing material A with material B. C. Removing material B. D. None of the above.arrow_forwardTwo flat plates of glass with parallel faces are on a table, one plate on the other. Each plate is 11.2 cm long and has a refractive index of 1.55. A very thin sheet of metal foil is inserted under the end of the upper plate to raise it slightly at that end, in a manner similar to that pictured in the figure (Figure 1). When you view the glass plates from above with reflected white light, you observe that, at 1.10 mm from the line where the sheets are in contact, the violet light of wavelength 410 nm is enhanced in this reflected light, but no visible light is enhanced closer to the line of contact.

Consider D>> d. Please use "*" B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For exponents (e.g. A²) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A* cos theta.
