When astronomers discuss the apertures of their telescopes, they say bigger is better. Explain why.
a) A wider aperture can observe a significantly larger portion of the sky. b) A wider aperture makes a telescope easier to aim. c) A wider aperture allows a telescope to collect more light, so it can produce images with higher resolution. d) A wider aperture allows a telescope to collect more light, so it can detect fainter light sources.
A 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.

- 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.arrow_forwardOf the following observing devices, the one that is designed to make observations at visible wavelengths is a.
