Question
The purpose of using a telescope with a large objective rather than a small one is
greater light-gathering power
greater magnification
better resolution
D. [both A and C
"A procedure that allows a number of telescopes to be used as one" describes
diffraction
interferometry
photometry
spectroscopy
The reason for using a long baseline in interferometry is to
increase the resolution of the observation
increase the amount of energy received from the source
decrease chromatic aberration
allow active optics to be used
