- 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.
- Astronauts observing from a space station need a telescope with a resolving power of 0.6 arc second at a wavelength of 530 nm and a magnifying power of 220. Design a telescope to meet their needs.What will its light-gathering power be, compared with a dark-adapted human eye? (Assume that the pupil of your eye can open to a diameter of about 0.8 cm in dark conditions.)(State the necessary primary diameter of the telescope, in m, and the ratio of the focal lengths below.)Geostationary satellites cannot be seen in a telescope from Albany because they are always directly over the Equator. True FalseWhich 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.
