1 Astronomical Telescopes and Instruments START EXIT Funded by Title V HIS Grant at LAMC and U.S Department of Education Corresponds to Ch 4 in book Astro by Seeds Prepared by: Julissa Garcia, Aramik Yousefian Hagop Hadjinian, Tatevik Grigoryan Activity director: Lilit Haroyan Faculty Advisor: Richard Rains

2 1. If a telescope has a large Aperture… HINT There is less light There is less diffraction None of the Above It has no power to resolve detail It has no power to resolve detail Exit

3 HINT There is less light There is less diffraction None of the Above It has no power to resolve detail Correct! next 1. If a telescope has a large Aperture… Exit

4 1. If a telescope has a large Aperture… Incorrect The larger the Aperture the less the diffraction (when images are hard to see). back next HINT Exit

5 It lessens the difficulty to see back Exit

6 2. What does a Refracting telescope use? HINT Glass lens Computer Rainbows Mirror Exit

7 HINT Glass lens Computer Rainbows Mirror Correct! next 2. What does a Refracting telescope use? Exit

8 2. What does a Refracting telescope use? HINT Exit Incorrect Remember Mirror Lens Reflect (reflecting telescope), whereas Glass Lens are Refracting telescope. back next

9 Galileo had a refracting telescope back Exit

10 3. According to the Spectrum of Visible Light… HINT Violet has long wavelengths Violet has long wavelengths Yellow has short wavelengths Yellow has short wavelengths Pink has the strongest wavelengths Pink has the strongest wavelengths Red has long wavelengths Exit

11 HINT Violet has long wavelengths Violet has long wavelengths Yellow has short wavelengths Yellow has short wavelengths Pink has the strongest wavelengths Pink has the strongest wavelengths Red has long wavelengths Correct! next 3. According to the Spectrum of Visible Light… Exit

12 back next 3. According to the Spectrum of Visible Light… Incorrect Red has longer wavelengths than blue, which are short. nextback HINT Exit

13 This is the color of tomatoes back Exit

14 4. A Photon is a: HINT A Photographic camera A Particle of light A red wavelength A sub particle of fungi Exit

15 HINT A Photographic camera A Particle of light A red wavelength A sub particle of fungi Correct! next 4. A Photon is a: Exit

16 Incorrect Photons are particles of light that we cannot see but move through light. back next 4. A Photon is a: Exit

17 Photons are passing through you right now through the computer screen back Exit

18 5. VLA stands for what? HINT Very Large Array Violet Length Array Radio Images of the Sky Vegetarians Love Asparagus Vegetarians Love Asparagus Exit

19 HINT Very Large Array Violet Length Array Radio Images of the Sky Vegetarians Love Asparagus Correct! next 5. VLA stands for what? Exit

20 Incorrect Very Large Arrays look like huge Dish satellites with antennas. back next 5. VLA stands for what? HINT Exit

21 It is a very large dish… back Exit

22 6. According to the Electromagnetic Spectrum: HINT Gamma Rays are the strongest Gamma Rays are the strongest X-Rays are the weakest None of the above Radio waves are strongest Radio waves are strongest Exit

23 HINT Gamma Rays are the strongest X-Rays are the weakest None of the above Radio waves are strongest Correct! next 6. According to the Electromagnetic Spectrum: Exit

24 Incorrect Gamma rays are deadly, followed by x-rays and other weaker forms of waves are microwave and radio (weakest). back next 6. According to the Electromagnetic Spectrum: HINT Exit

25 back They appear in the right side of the spectrum… Exit

26 7. UV wavelengths… HINT Are Long wavelengths Are short wavelengths All wavelengths Has No wavelengths Exit

27 HINT Are Long wavelengths Are short wavelengths All wavelengths Has No wavelengths Correct! next 7. UV wavelengths… Exit

28 Incorrect In the spectrum everything on the left is longer wavelengths, and everything on the right has shorter wavelengths, the UV rays are in middle left. back next 7. UV wavelengths… HINT Exit

29 They are next to visual lights on the left side of the spectrum. back Exit

30 8. VLBI stands for what? HINT Very Large Batman Ice Very Large Base Infrared None of the above Very Large Base interferometer Very Large Base interferometer Exit

31 HINT Very Large Batman Ice Very Large Base Infrared None of the above Very Large Base interferometer Correct! next 8. VLBI stands for what? Exit

32 8. VLBI stands for what? HINT Exit Incorrect VLBI’s use Interferometry in radio arrays to get images and information from space. back next

33 It uses interferometry… back Exit

34 HINT The study of celestial objects through radio The study of celestial objects through radio The study of astronomy through stars The study of astronomy through stars None of the above The study of volcanic activity 9. Radio astronomy is… Exit

35 HINT The study of celestial objects through radio The study of astronomy through stars None of the above The study of volcanic activity Correct! next 9. Radio astronomy is… Exit

36 9. Radio astronomy is… HINT Exit Incorrect Radio includes all aspects of space discovery through radio. back next

37 Astronomy is the study of the universe…radio implies… back Exit

38 10. Chromatic aberration is seen in which type of telescope? HINT Reflecting telescopes Radio telescopes Galileo’s telescope Refracting telescopes Exit

39 HINT Reflecting telescopes Radio telescopes Galileo’s telescope Refracting telescopes 10. Chromatic aberration is seen in which type of telescope? Correct! next Exit

40 10. Chromatic aberration is seen in which type of telescope? Incorrect Chromatic aberration is when the colors get a “smudged” look. back next HINT Exit

41 These are telescopes with glass lens back Exit

42 EXIT TRY AGAIN TRY AGAIN TRY AGAIN TRY AGAIN
