wavelength of 600 nm compared to that of a 300-ft, single-dish radio telescope
that observes at a wavelength of 21 cm?
15.
Explain three major
advantages of CCDs over other imaging techniques.
16.
What is quantum
efficiency?
17.
When you look at the
side of a CD where the data are stored, why do you observe a rainbow?
18.
Why is it difficult to
view low-surface-brightness, such as the Andromeda Galaxy, with the naked eye?
Does the view improve with the use of a telescope? What is needed to get a
bright, clear view of the Andromeda Galaxy, as commonly seen in pictures?
19.
Explain how a
spectrograph works.
20.
Explain the difference
between dispersion and diffraction. How can both phenomena be used to create a
spectrum?
21.
Where is the best place
to put a ground-based optical telescope? Discuss the reasons for your
selection.
22.
Name two reasons why
astronomers might use a space telescope over a ground-based telescope.
23.
Why don’t astronomers
put all telescopes in space?
24.
Why does combining the
light from smaller telescopes give observation results comparable to those of a
single large telescope with a diameter equal to the separation of the two
smaller telescopes?
25.
Discuss two advantages
of flyby missions over orbiters in exploring planets and moons in the solar
system.
26.
What are some
advantages and disadvantages of using landers to explore the solar system?
27.
What are gravitational
waves? Have astronomers been able to detect them yet?
28.
Discuss two tools that
modern astronomers use to explore the cosmos that are different from
traditional optical telescopes and give an example of how and why each is used.
29.
How much larger is the
light-gathering power of a 10-inch telescope than the human eye?
30.
What is the diffraction
limit of a 4-m telescope observing at a wavelength of 650 nm?
