Solved in 2 steps
- The largest telescopes in the world are used to detect: a)x-ray. b)radio wave. c)visible light. d)ultraviolet.The light-gathering power of a telescope is directly related to the area of the telescope's primary mirror. A mirror with four times the diameter of another mirror collects how many times more light as the smaller mirror does in the same amount of time? (Numerical answer only, please.)Geostationary satellites cannot be seen in a telescope from Albany because they are always directly over the Equator. True False
