30. The index of refraction of the transparent mineral beryl is approximately 1.6. Transparent 33. At what angle is the first-order line for violet light with a wavelength of 400 nm produced by quartz has an index of 1.54. Diamond has an index of 2.42. Based on these facts, which a diffraction grating that has 1.00 x 10* lines per centimeter? statement is true? Assume light travels from air into each substance. All three minerals bend light to the same extent. Quartz bends light more than beryl does. Beryl bends light more than quartz does. Both beryl and quartz bend light more than diamond does. 31. Two slits are separated by 1.72 x 105 m, and the screen is 0.650 m away from the slits. Monochromatic violet light with a wavelength of 450 nm passes through the slits. How far from the central band does the first band of violet light appear? 34. Two stars that are 1.50 x 108 km apart are viewed through a telescope at a distance of 10.5 light years. What is the smallest diameter of telescope that could resolve these two objects? Use a wavelength of 2 = 550 nm in your calculations. 32. A certain diffraction grating has 6.00 x 10' lines per centimeter. The screen is 0.400 m from the grating. Monochromatic light shines on the grating, and the first-order line in the pattern is 12.9 cm from the central line. What is the wavelength of the light in nanometers? 35. The Rayleigh criterion cannot be used to calculate the resolving power of flat glass c. microscopes telescopes d. the human eye in
