Physics 107 Hauck Chapter 6 1. Our eye focuses light by bending it through our lenses. A glass lens also bends light the same way. The focal point in where the image appears in focus. 2. Cameras give a recorded image and we can change the exposure time. CCDs are much more sensitive to light, they have a much wider dynamic range than photograph film and images can be processed. 3. Two properties of a telescope are its light collecting are and its angular resolution. 4. Diffraction limit is the angular resolution that a telescope could achieve if it were limited by only the interference of light waves. 5. A refracting telescope operates like an eye and uses a transparent glass lenses to focus the light from distant objects. A reflecting telescope uses a curved primary mirror to gather light. 6. Astronomical observations are broken into three categories, imaging which yields photos of objects, spectroscopy which spectra is obtained

Unformatted text preview: and studied and timing which track how an object changes over time. 8. With spectracel resolution, the higher the resolution, the more detail we can see. It is harder to achieve because it takes more time. 9. Light pollution, twinkling and atmospherica turbulence affect ground-based observations. 13. Yes, this makes sense. 16. Yes, the photograph could be capturing less detailed version showing the system, not individual stars. 23. A-two times. 24. B-one point of light that is the blurred image of both stars. 25. A-telescopes size 26. A-larger 28. C-air in our atomosphere 30. A-earths orbit 31. C-interferometry. 32. C-both the light-collecting area and the angular resolution of a much larger telescope. 34. a. timing- it is an observance over time. b. . imaging- to study a photograph c. spectroscopy-needs to use light and time to determine distance....
