If an optical telescope focusing light of wavelength 558 nm had a perfectly ground mirror, what would have to be the minimum diameter of its mirror so that it could resolve a Jupiter-size planet (the diameter of Jupiter is 1.38×108 m) around our nearest star, Alpha Centauri, which is about 4.30 light years from earth? (1 light year = 9.46×1015 m ).

Sometime around 2022, astronomers at the European Southern Observatory hope to begin using the E-ELT (European Extremely Large Telescope), which is planned to have a primary mirror 42 m in diameter. Let us assume that the light it focuses has a wavelength of 520 nm. (1 light-year =9.461x 1015 m) Note: Jupiter's Diameter di 1.43 x 108 m 1) What is the most distant Jupiter-sized planet the telescope could resolve, assuming it operates at the diffraction limit?

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)

The Hubble Space Telescope (still operational) has a mirror with a diameter of 2.4 m. What is the maximum resolution of Hubble when observing Mars at closest approach (typically 7.5 x 1010 m away)? Since Mars is mostly red, assume the light is reddish, with a wavelength of 630 nm. Could Hubble resolve the Endeavor crater (diameter 22 km) on Mars? 1. 2. Calculate the angle of incidence at which light reflecting off of crown glass (with an index of...

Suppose your Newtonian reflect has an objective mirror 10 cm (4 inches) in diameter. a) What is the telescope's diffraction-limited angular resolution when used with yellow light of wavelength 600 nm? b) A binary star is a system of two stars orbiting each other. Suppose you are observing a binary star consisting of two yellow stars having an angular separation of 0.5 arc-seconds. Will your telescope be able to resolve the two stars? Explain your answer. c) Would you be...
