Use diagrams to describe how the following types of telescope collect light from a single point-
source at infinity, and form a focused image in the focal plane:
(i) refractor
(ii) Newtonian reflector
(iii) catadioptric telescope.
A telescope with focal ratio f/10 and diameter D = 0.5 m has a CCD detector placed at its focal
plane. The CCD chip has dimensions 3 × 3 cm2
. Determine the size of the field of view that can
be imaged on the CCD detector in units of arcminutes × arcminutes, and state whether or not an
image of the full moon can be captured. Assume the angular diameter of the full moon is 30
arcminutes.
Telescopes do more than just magnify images. In fact, if all they did was magnify images Galileo would have never seen the moons of Jupiter. What other important thing does the telescope do?
a)The telescope is better at tracking movement than the naked eye is.
b)The telescope is able to take disorderly rays and collimate them.
c)The telescope is able to discern more colors than the naked eye can.
d)The telescope is able to gather more light than the naked eye can.
Kepler's design allowed him to achieve better image quality and higher magnifications than Galileo's. However, his design has a significant drawback. What is it?
a) Kepler's telescope has rays intersecting each other, which creates the possibility that they will interfere with each other.
b) Kepler's telescope is less able to collimate chaotic incoming light.
c) Kepler's telescope collects less light.
d) Kepler's image is inverted, while Galileo's is upright.
You are using a telescope is to resolve two distant stars as well as possible.
Which of the following modifications will increase the resolution of the telescope?
Question 8 options:
Use a filter to filter out all but the red light.
Use a filter to filter out all but the blue light.
Use a lens of smaller diameter
Use a lens of larger diameter
None of these modifications will impact the resolution of the telescope.

- 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_forwardWhy are the largest visible-light telescopes in the world made with mirrors rather than lenses?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.
