Question Details wolfl 30.E.13. 1742A001 The mirriors in Fig.3O.19 make a 60" angle. A light ray enters parallel to the symmetry axis, as shown. Figure 30.19a. (a) How many reflections does it make? f I I 3i(b) Where and in what direction does it exit the mirror system? off the second mirror parallel to the incident ray off the second mirror at an angle of 60" off the first mirror and normal to it off the first mirror at an angle of 60" [] off the first mirror, along and in the opposite direction to the incident ray Question Details Wolfl 30.E.19. 17544021 A light ray propagates in a transparent material at 120 to the normal to the surface. When it emerges into the surrounding air, it makes a 19o angle with the normal. What is the refractive index of the material? r-.- L li_ tsrl Question Details Wolfl 30.E. 17. 17544681 Information in a compact disc is stored in "pits" whose depth is essentially one-fourth of the wavelength of the laser light used to "read" the information. That wavelength is roughly 779 nm in air, but the wavelength on which the pit depth is based is measured in the n = L.57 plastic that makes up most of the disc. Find the pit depth. i-tdn*
