| Question | Answer |
| Magnification | Best known
Least important |
| Light Gathering Power | Most important |
| Resolution | Most difficult to understand
Ability to see fine detail
Scopes resolution is dependent on its aperture |
| MMT | Multiple Mirror Telescopes |
| Blue Shifted | Object coming toward you |
| Red Shifted | Object going away from you |
| Continuous Spectrum | Unbroken band of colors
Source sends out light of all visible wavelengths
Glowing Solid
Glowing Liquid
Hot compressed gases inside a star |
| Spectroscope | Separates starlight into its colors to identify different wavelengths |
| Visible Spectrum | Band of colors when starlight is separated |
| Bright Line Spectrum | Emission Spectrum
Comes from chemical elements when they are in the form of a glowing thin gas or vapor |
| Dark Line Spectrum | Continuous spectrum with dark lines where light is absorbed |
| CCD | Charged Couple Device
Group of photocells electrons collect where light strikes device
Observed brightness is directly proportioned to the area of a telescope's mirror and to the square of the mirror |
| Atmospheric Blurring | Looks like asphalt on a hot day |
| Schmidt Telescopes | Uses both refracting lens and reflecting mirror
Creates very wide angle views
Best known: Hubble |
