A. turning a TV off with a remote control B. turning a light switch on and off C. listening to music with a headset D. setting a timer to start an oven Use the diagram below that shows the distance from Earth to Proxima Centauri to answer question 2. 2. Which of these instruments should you use to view Proxima Centauri? A. binoculars B. magnifying glass C. telescope D. microscope 3. Early telescopes showed stars as only points of light, while the planets appeared to be much larger, providing evidence that stars must… A. be more plentiful in our solar system than planets. B. travel in elliptical orbits like planets. C. be much farther from Earth than planets. D. reflect much more light than planets.

Types of Telescopes Telescope Refracting Telescope Reflecting Telescope Radio Telescope Use How it Works Produces magnified images of distant objects Produces magnified images of distant objects Collects radio waves from space Uses a convex lens to bend and focus light Uses mirrors to reflect and focus light Large dish reflects and focuses waves to receiver 7. According to the table, a refracting telescope focuses light using a… A. convex lens B. mirror C. dish D. receiver 8. In 1993 the Hubble Space Telescope had its largest mirror repaired in space. According to the chart, the Hubble Space telescope must therefore be….
