Based on being able to detect its wavelength, and cost of location, which telescope should be funded?
(A) A gamma ray detector in Antarctica.
(B) An ultraviolet detector in the Mojave desert.
(C) A near-infrared telescope on an aircraft.
(D) A radio telescope in space.
Correct answer: (C)
Gamma rays and ultraviolet waves cannot be detected at ground level, due to absorption of these wavelengths by the atmosphere. A near-infrared telescope on an aircraft would be able to detect signals at much less cost than a radio telescope in space.
