smaller, convexsecondary mirror to reflect light back through a hole in
the primary.

in the faintest, mostdistant galaxies.
Answer:
FALSEDiff: 2

diameter of its primaryobjective.
Answer:

now in service.Answer: FALSE

14) The 400″ Keck reflector can see objects 100 times fainter than the 40″
Yerkes lens.
Answer:
TRUEDiff: 3
Section Ref.: 3.2
15) Radio telescopes have poorer angular resolution than optical telescopes
because radio waveshave a much longer wavelength than optical waves.
Answer:
TRUEDiff: 1

refractors.Answer: FALSE
Diff: 1

causes this effect.Answer: TRUE
Diff: 1
Section Ref.: 3.3

adaptive optics.Answer: FALSE
Diff: 2
Section Ref.: 3.3
19) In the future, adaptive optics will greatly enhance the resolution of
the Hubble SpaceTelescope.
