- Astronauts observing from a space station need a telescope with a resolving power of 0.5 arc second at a wavelength of 570 nm and a magnifying power of 280. Design a telescope to meet their needs. (State the necessary primary diameter of the telescope, in m, and the ratio of the focal lengths below.)Astronauts observing from a space station need a telescope with a resolving power of 0.4 arc second at a wavelength of 530 nm and a magnifying power of 300. Design a telescope to meet their needs. (State the necessary primary diameter of the telescope, in m, and the ratio of the focal lengths below.) Dtelescope= m Feyepiece Fprimary = 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.) LGPtelescope LGPeye =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.)
- 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 FalseCompare the light-gathering power of a 10 m Keck telescope with that of a 0.9 m telescope.
- Suppose you want a telescope that would allow you to see distinguishing features as small as 6.5 km on the Moon some 384,000 km away. Assume an average wavelength of 550 nm for the light received. What is the minimum diameter of the mirror (in centimeters) that you could use in the telescope?Why is it that radio telescopes need to be so larger or organized in arrays?
