Question
The Apollo 11 mission landed on the Moon in 1969. Moon hoax enthusiasts often cite a lack of teloscopic evidence for hardware they left behind. The Hubble
Space Telescope (HST) is the largest orbiting telescope, with a 2.4-
meter aperture mirror. At closest approach, the HST-moon distance is
376,000 km.

Spring 2010 Physics 214* Sample Final Exam 22. The Apollo 11 mission landed on the Moon in 1969. Moon hoax enthusiasts often cite a lack of teloscopic evidence for hardware they left behind. The Hubble Space Telescope (HST) is the largest orbiting telescope, with a 2.4- meter aperture mirror. At closest approach, the HST-moon distance is 376,000 km. By approximately what factor would we have to increase the HST mirror aperture to resolve the lunar rover left by the Apollo 11 astronauts under the most optimistic circumstances? Use a wavelength of 700 nm for the light being detected by the HST and require that we need to resolve 15 cm features in order to identify it. a. Factor 10 b. Factor 100 c. Factor 1000 d. Factor 10000 e. Factor 100000 23. Light of unknown wavelength falls on a tiny pinhole. The pattern created by the pinhole has its first diffraction minimum at an angle 2 from the center line. In a second experiment light falls on a pinhole with a diameter that is half of that in the first experiment. What is the angle, emin, of the first diffraction minimum for the second (smaller) pinhole? a. min b. 0 2 min c. min. d. 0 min e. 0 16 minExplanation / Answer
solution for Q23
we know
sin(theta)=m*wavlength/diameter
if diameter=half
theta will be double so 4 degree
