If you have not done so, please read Chapter 3, Section 3.1, "Properties of Light," pp 92-96. Answer "Questions for Review," p 116, #1-3 and post the answers on edmodo (if you haven't handed them in on paper by Friday.)

New:

READ Sections 3.2 "The Electromagnetic Spectrum: Beyond Visible Light", pp pp 96-101; 3.3, "Atoms," pp 101-104; and 3.4, "The Origin of Light," pp 104-105

ANSWER Rev. Questions p 116, #4, 5, 8, and 9.
Also, ANSWER these questions:

1. How did Sir William Herschel show that heat from the Sun is related to visible light?

2. How do infrared and ultraviolet radiation differ from visible light?

3. What is the range of radio waves?

4. Why are microwaves and gamma waves so difficult to study from the earth's surface?

5. List, in order from LEAST energy to GREATEST energy generated, the types of EM (electromagnetic) radiation.

6. List, in order from shortest wavelength to longest wavelength, the types of EM radiation.

7. HOW are the answers for questions #4 & #5 related?

8. A burner on an electric stove, as it heats up, glows dull red at first but after five minutes glows a bright yellow. How does the color of the burner relate to the temperature of the burner?

9. What is Wein's Law?

10. What is a blackbody? Why are blackbodies excellent absorbers AND emitters of energy?

11. Describe the parts and structure of an atom.

12. How are electrons similar to planets in a solar system? How are they different?

13. What is an element? How is the identity of an element determined?

14. How are electrons bound to their nucleus?

15. What is happening to an electron in when its atom is "excited?" What is happening to the atom's energy?

16. What is the Law of Conservation of Energy? Thinking of this law, what must happen when an atom loses energy?

17. What is emission?

18. What is absorption?

Chapter 1, sections 1.2 & 1.3.

You will be tested on the contributions of the historical astronomers (the Greeks plus Ptolemy), Copernicus, Kepler and Galileo. NO math. NO temperature conversion. NO Newton or Laws of Motion.

KNOW why the painted walls of the Cave of Lascaux (in southwest France) and Stonehenge are notable to astronomy.

KNOW Kepler's Three Laws of Planetary Motion.

KNOW the difference between geocentricism and heliocentricism. (Which is reality?)

KNOW what Occam's Law is.
