The South African Large Telescope has an aperture of 10.2 meters and was made to observe visible light with a wavelength of 500 nanometers. What is the maximum resolution, or diffraction limit, of this telescope in arcseconds? (Make sure to show all calculations with units and show/explain any conversions.)
what advantages does a catadioptric telescope have over a reflecting telescope? what is its disadvantages?
The light-gathering power of a telescope is directly related to the area of the telescope's primary mirror. A mirror with four times the diameter of another mirror collects how many times more light as the smaller mirror does in the same amount of time? (Numerical answer only, please.)

- Name the two spectral windows through which electromagnetic radiation easily reaches the surface of Earth and describe the largest-aperture telescope currently in use for each window.arrow_forwardMany decades ago, the astronomers on the staff of Mount Wilson and Palomar Observatories each received about 60 nights per year for their observing programs. Today, an astronomer feels fortunate to get 10 nights per year on a large telescope. Can you suggest some reasons for this change?arrow_forwardTelescopes can now be operated remotely from a warm room, but until about 25 years ago, astronomers worked at the telescope to guide it so that it remained pointed in exactly the right place. In a large telescope, like the Palomar 200-inch telescope, astronomers sat in a cage at the top of the telescope, where the secondary mirror is located, as shown in Figure 6.6. Assume for the purpose of your calculation that the diameter of this cage was 40 inches. What fraction of the light is blocked? Figure 6.6 Focus Arrangements for Reflecting Telescopes. Reflecting telescopes have different options for where the light is brought to a focus. With prime focus, light is detected where it comes to a focus after reflecting from the primary mirror. With Newtonian focus, light is reflected by a small secondary mirror off to one side, where it can be detected (see also Figure 6.5). Most large professional telescopes have a Cassegrain focus in which light is reflected by the secondary mirror down through a hole in the primary mirror to an observing station below the telescope.arrow_forward
