The primary mirror on a telescope that orbits 600 km above Earth has a diameter of 2.4 m. a) Calculate the minimum angular separation that it might resolve for visible light. b) Assume that the telescope is viewing Earth’s surface. What is the separation of the most closely spaced objects that it might resole?

3) (10 pts) The Thirty Metre Telescope (TMT) is a 30m diameter telescope to be built on Mauna Kean in Hawaii. The Hubble Space Telescope is a 2.4m diameter telescope in orbit around the Earth. a) (2.5 pts) What are the angular resolutions of both telescopes when observing in "visible" light (1 = 550 nm)? How many times better or worse is the HST compared to the TMT? b) (2.5 pts) What are the angular resolutions of both telescopes when...

The next generation of large telescopes includes a proposed 30 m telescope on top of Mauna Kea in Hawaii. If this telescope is pointed towards two identical stars which orbit around each other at the Neptune-Sun distance of 4.5 billion km = 4.5 × 10^12m, what is the maximum distance in meters between Earth and the two stars at which the telescope can still resolve them? Assume that the telescope observes light with a wavelength of 500 nm. The answer...

Constants Part A The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. A typical amateur astronomer's telescope may have a 7.0 in. -diameter mirror What is the minimum angular separation (in arc seconds) of two stars that can be resolved with a 7.0 in. scope? (Take ? to be at the center of the visible spectrum, about 550 nm, and note that 1 arc sec 1/3600 ) Express your answer using two...

The Hubble Space Telescope has a mirror diameter of 2.4 m. Suppose the telescope is used to photograph stars near the center of our galaxy, 30,000 light years away, using red light with a wavelength of 720 nm . A) What's the distance (in km) between two stars that are marginally resolved? The resolution of a reflecting telescope is calculated exactly the same as for a refracting telescope. B) For comparison, what is this distance as a multiple of the...

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...

6. The Hubble Space Telescope (HST) has a 2.4m diameter primary mirror, which you may assume to be diffraction limited. The HST is used to image an object located at a distance of 4000km away from the HST. Estimate the minimum feature size that may be resolved using yellow light (wavelength=580nm) on the distant object? [10 marks]

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...

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? (Express your answer...

Question 1: [20 Points] a) The primary mirror of the orbiting Hubble Space Telescope has a diameter of 2.50 m. Being in orbit, this telescope avoids the degrading effects of atmospheric distortion on its resolution. The Hubble Space Telescope is observing light source coming from a very far away galaxy as shown in the figure above. The scientists are debating whether the light being observed is coming from a single light source or two different light sources. You as a...
