TOTAL POINTS 9
1.Bigger is better when it comes to telescopes, because larger telescopes collect more light and produce higher resolution images. Resolution, however, is also proportional to the wavelength of light being observed: (shorter/longer) waves deliver (lower/higher) angular resolution.
1 poin
2.True or False: The largest telescopes in the world today are refracting telescopes and use lenses to collect and focus light.
1 point
3.The Earth’s atmosphere is opaque to many wavelengths of light and only a few are able to penetrate all the way through to the surface. Based ONLY on the wavelengths of light which make it through the Earth’s atmosphere, choose one of these telescopes that should receive funding:
1 point
4.Every few years even the mirrors on very large telescopes need to be recoated. A very thin coating of _________ is sputtered onto large telescope mirrors to create the reflecting surface on top of the glass.
1 point
5.The secondary mirror in a telescope with adaptive optics can be adjusted…
1 point
6.Interferometers have been traditionally incorporated into ________ telescopes.
1 point
7.For an interferometer to have the sharpest image resolution, it is better to have:
1 point
8. The Large Synoptic Survey Telescope, and it’s large CCD detector will produce huge amounts of data that will allow astronomers to survey the night sky and do a fundamentally new type of science called “celestial cinematography”. We will learn new things about the universe by looking at it in which of these new domains:
1 point
9.True or False: Telescopes are put into space so that they will be a little closer to the stars.
1 point
