Use the following information to answer the next three questions. A student follows three procedures to study the properties of laser light. She uses a laser that emits monochromatic light that has a wavelength of 634 nm. Procedure Observation The student first shines the laser The path of the refracted light through a crystal that has ray is recorded. an index of refraction of 1.53. II The student shines the laser light An interference pattern is through a diffraction grating that projected onto a screen. has 5.00 x 10' lines/m. III The student shines the laser light No electrical current is upon a photovoltaic cell that is measured. connected to an ammeter. 5. The energy of one photon emitted by the laser is A. 4.20 x 10 31 J B. 3.14 x 10-28 J C. 3.14 x 10-19 J D. 4.20 x 10 40 J Numerical Response #3 In procedure II, the angle between the central maximum and the first bright spot of the interference pattern is (Record your three-digit answer on your Scantron) 6. In order to produce an electrical current in procedure III, the student must use electromagnetic radiation that has a _ i wavelength or a photovoltaic plate that has a _ii work function than those she actually used in procedure III. The statement above is completed by the information in row Row i ii A. shorter larger B. longer larger C. shorter smaller D. longer smaller
