5 True/False Questions
Very Large Array → A telescope's main focusing mirror.
atmospheric blurring → Color distortion in an image produced by a lens, cause by the inability of the lens to bring various colors of light to focus at a single point.
active optics → A technique used to increase the resolution of a telescope by deforming the shape of the mirror's surface under computer control while a measurement is being taken, to undo the effects of atmospheric turbulence.
eyepiece → An instrument used to better observe the EM radiation from faraway objects. Also called a "light-bucket".
primary mirror → A telescope's main focusing mirror.
