Question

Problem 5 (18 points) The Hubble Space Telescope has an aperture of 2.4 m and focuses visible light (380- 750 nm). The Arecibo radio telescope in Puerto Rico is 305 m (1000 ft) in diameter and focuses radio waves of wavelength 75 cm. Under optical viewing conditions, what is the smallest crater that each of these telescopes could resolve on our moon? Earth-Moon distance = 3.8 × 108 m. a)

Answer 1

b) Here we have the formula 1.22AD 1.22 x380x10-9 x D 0.3- 2.4 2.4x0.3 1.22 x380x10 -1553062m c) Since the crater that Arecibo telescope can resolve is of greater range it will have the better resolution

b) Here we have the formula 1.22AD 1.22 x380x10-, D 0.3 = 2.4 2.4 x0.3 1.22x380x109 = 1553062m c) Since the crater that Arecibo telescope can resolve is of greater range it will have the better resolution
