Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points Is diffraction more pronounced through a small or a large opening? 1. small 2. It depends on the frequency of the light. 3. large 002 10.0 points Consider the setup of a single slit experiment. y 3 L a S 1 S 2 viewing screen 15 Find the height y 3 , where the third mini- mum occurs. Use a small angle approximation sin = tan . 1. y 3 = 5 L a 2. y 3 = 4 L a 3. y 3 = 9 2 L a 4. y 3 = 2 L a 5. y 3 = 3 L a 6. y 3 = 5 2 L a 7. y 3 = 7 2 L a 8. y 3 = 1 L a 9. y 3 = 11 2 L a 10. y 3 = 3 2 L a 003 10.0 points Light from a He-Ne laser of wavelength 529 . 4 nm is incident on a single slit. What is the minimum width for which no diffraction minima are observed? Answer in units of nm. 004 10.0 points A binary star system in the constellation Orion has an angular separation between the two stars of 4 . 89 10 6 rad. If the wavelength is 572 nm, what is the smallest diameter a telescope can have and just resolve the two stars? Answer in units of cm. 005 10.0 points A good diffraction grating has 2590 lines / cm. What is the distance between two lines in the grating? Answer in units of cm. 006 (part 1 of 2) 10.0 points A spectrometer uses a grating with 12700 lines / cm....
