- Why is it advantageous to use a large-diameter objective lens in a telescope? (a) It diffracts the light more effectively than smaller-diameter objective lenses. (b) It increases its magnification. (c) It enables you to see more objects in the field of view. (d) It reflects unwanted wavelengths. (e) It increases its resolution.arrow_forwardPeople 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_forwardA telescope that suffers from chromatic aberration and has a low light-gathering power is most likely a(n) a. small diameter reflecting telescope. b. small diameter refracting telescope. c. large diameter refracting telescope. d. large diameter reflecting telescope e. infrared telescope.arrow_forward
- Which of the following is NOT an advantage that a REFLECTING telescope has over a REFRACTING telescope? a. glass need not be as of high quality. b. can see stars during the day. c. less expensive. d. no chromatic aberration. e. mirror can be supported more fully than lens. 2. When looking at a cross section diagram of a planet, why might the layer of a planet between the core and crust appear green? a. There is a lot of methane in that layer.b. To represent chlorophyll in the atmosphere. c. This layer is typically made of green jade.d. Green is the middle color of ROYGBIV, so it was used to represent the middle layer. e. Because such layer is composed of rocks containing a lot of Olivine.arrow_forwardA new generation of telescopes is currently being built that overcomes the limitations of the older large telescopes. Some of these new telescopes a. use segmented mirrors. b. use mirrors that are very thin. c. use active optics to control the shape of the mirror. d. do all of the above. e. do none of the above.arrow_forward2. If a telescope with focal length 30 cm "sees" an object taking up 2° of its view, how big is the image in the telescope? 3. If an object makes an image that's 0.5 mm on your retina, how many degrees of your view does it occupy? 4. When you zoom into an object optically with your camera (not electronic zoom), does the lens extend or contract? Why? 5. Why is a ground-based x-ray telescope not a great idea? 6. What is the resolution in seconds of telescope with a 0.5 m diameter lens at visible light? 7. Some telescopes are dual-purpose: they detect visible light and infra-red. Were the telescope in the question above capable of this, would it have higher resolution in infra-red or lower (compared to visible light)? 8. What diameter lens do you need on a telescope that can resolve up to a thousandth of a second? 9.

The resolving power is reduted to 1/4 of its original value. e.The resolving power does/not change unless the focal length changes. f.None of the abovearrow_forwardA telescope is used to resolve two distant stars. By what factor will the resolution of the telescope change if the diameter of the lens is doubled? a)The resolution will increase by a factor of 4 b)The resolution will increase by a factor of 2 c)The resolution will not change, although more light will be collected. d)The resolution will decrease by a factor of 2 e)The resolution will decrease by a factor of 4 f)arrow_forwardThe instrument that can record the image of a faint object in the least amount of observing time is the a. human eye. b. photographic plate. c. photometer. d. charge-coupled device (CCD). e. spectrometer.arrow_forward
