Step by step
Solved in 3 steps
- two reflecting telescopes have the same angular resolution, but one of them uses visible light and other uses infrared. Which telescope must have the larger primary mirror? visible light telescope or infrared telescope?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.)
- A powerful telescope can observe an object down to about the 30th magnitude in the B-band. To what distance can this kind of telescope observe a star such as the Sun? What kind of energy flux is observed at this telescope in terms of the solar constant? (Show your work for all calculations)Compare the light-gathering power of one of the 10-m Keck telescopes with that of a 0.5-m telescope.Geostationary satellites cannot be seen in a telescope from Albany because they are always directly over the Equator. True False
- Which of these telescopes that detect visible and infrared light has the largest mirror, that is, the most "light gathering" capability? Hubble Space Telescope, now in low Earth orbit. The Vera Rubin telescope now under construction. in Chile. James Webb Space Telescope, to be launched by NASA and ESA this month. Palomar telescope, in California north of San Diego.Theoretically (that is, if seeing were not an issue), the resolution of a telescope is inversely proportional to its diameter. How much better is the resolution of the ALMA when operating at its longest baseline than the resolution of the Arecibo telescope?Why is it that radio telescopes need to be so larger or organized in arrays?
