Imagine that you are the head of a funding agency that can afford to build only one telescope. Which of the four proposed telescopes below
would be best to support?
O A. a radio telescope in orbit above the Earth
B. A gamma ray telescope in orbit above the Earth
O C. An x-ray telescope located on a mountain in Peru
D. An ultraviolet telescope located in the Mojave desert
What is the magnification of an astronomical telescope whose objective lens has a focal length of 78 cm and whose eyepiece has a focal length of 2.8 cm? The telescope is set so the image of the eyepiece is at infinity (so the viewer’s eye is “relaxed”). What is the overall length of the telescope?
Sketch the situation, defining all your variables
Please sketch it, this is most important.
Look at the central transparent area of someone’s eye, the pupil, in normal room light. Estimate the diameter of the pupil. Now turn off the lights and darken the room. After a few minutes turn on the lights and promptly estimate the diameter of the pupil. What happens to the pupil as the eye adjusts to the room light? Explain your observations.

- People are often bothered when they discover that reflecting telescopes have a second mirror in the middle to bring the light out to an accessible focus where big instruments can be mounted. “Don’t you lose light?” people ask. Well, yes, you do, but there is no better alternative. You can estimate how much light is lost by such an arrangement. The primary mirror (the one at the bottom in Figure 6.6) of the Gemini North telescope is 8 m in diameter. The secondary mirror at the top is about 1 m in diameter. Use the formula for the area of a circle to estimate what fraction of the light is blocked by the secondary mirror. 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_forwardQuite often advertisements appear for telescopes that extol their magnifying power. a) Is this a good criterion for evaluating telescopes?
