ASH SCI 151 Week 3 Content Question latest

1. What are electromagnetic waves? What other types of electromagnetic radiation besides light? Order the types of electromagnetic waves from shortest to longest wavelength. How you determine the temperature, composition, and motion of an object from its light spectrum?

2. What is the Hertzsprung-Russel (H-R) diagram? What attribute is listed on each axis. Compare stars in the upper left of the Main sequence vs. the stars at the lower right. Which ones are Larger? More Luminous? More massive? Hotter?

3. Summarize the complete lifecycle of stars from birth to death. Describe how the lifespan of a low mass star compares to a high mass star. Which lives longer and why?

4. What kind of stars eventually become white dwarfs? What kind eventually become supernovae? Where is the Sun in its lifecycle? What will be the ultimate fate of the Sun?

5. Explain the major designs of telescopes and discuss their strengths and weaknesses.

6. Describe the best places to build ground-based telescopes and why astronomers choose those places.

7. Contrast the strengths and weaknesses between building telescopes on the Earth, in orbit, or even on the Moon.

1. The relationship between the speed of light, C, wavelength, L , and frequency, F is

2. The moon is 375,000 Km from Earth. You shine a

laser with a wavelength of 1 centimeter at the moon. About how long did it take for the light leaving your laser to reach the Moon?

3. Radio Waves are

4. A star whose spectrum peaks in the Infrared is always

5. The Hubble Space Telescope obtains higher resolution images than most ground based telescopes because

6. Solar Brightening is due to

7. The time it takes energy created inside the Sun’s core through nuclear fusion to eventually leave the Sun as a visible photon is

8. What causes the 11-year cycle of solar activity?

9. Select the best statement below regarding the structure of the Sun

10. A Star converts 10 Million Kilograms of hydrogen each second into energy. The amount of energy this corresponds is equivalent to a power of

11. At the Center of the Sun the nuclear fusion process converts hydrogen into

12. Assume the Sun convertsthrough Hydrogen Fusion about 700 Million tons of Hydrogen each second into Helium, and Energy. How long in years would it take for the Sun to lose the equivalent of one Earth massin Hydrogen?

*The mass of the Earth = 6 x 1024 Kg. and 1 Ton = 900 Kilograms.

1.The Star Sirius looks brighter than Alpha Centauri, does this mean that Sirius is closer to the Earth than Alpha Centauri. ______

2.The Star Sirius is 8 Light years from earth…. If a star with equivalent luminosity to Sirius was 16 light years from Earth, would it appear ¼ as bright? _____

3. Blue stars have hotter surface than red stars? ___

14. An H-R diagram is use for plotting

15. The Sun is a main sequence Star today. When the Sun becomes a Red giant it will be characterized compared to the Sun today as having a

16. Stars form most easily in Molecular clouds that are

17. What would you most find if you could return to the SUN 10 Billion years

18. Which Sequence defines the life cycle of a large star of 10 Solar Masses from start to end.

19. What Method is most often used to measure the distance of star that is within 100 Light Years from Earth

20. The distance from Earth to the star Betelgeuse is about 430 Light Years. If it were to explode as a supernova it would be the brightest star in the Sky. Right now the brightest star other than the Sun is Sirius with a Luminosity of 26 L sun and a distance of 8.6 Light Years. If Betelgeuse reached a maximum Luminosity of 10 8 L Sun, how much brighter in our sky would the Betelguese Supernova be compared to Sirius.

27. The amount of Solar power that reaches the Earth’s Surface on a clear day when the Sun is directly overhead is about

28. Which statement is False

29. A Black Hole Can be indirectly detected by

30. Explain why massive stars stay on the main sequence for much shorter times than average stars like the sun. (Minimum 100 words)
