1) Can you name every symbol on the equation sheet and do you know their units? 2) Do you recognize every equation on the equation sheet and know when to use it? 3) Can you do all of the calculations on the assignments using the formula sheet? You also need to be familiar with the important concepts covered in lectures. For example, you can answer the following questions: Lectures 1-2 1) Which ancient astronomer developed the first capability for predicting planetary motion? 2) Who was the first person to develop the idea that the Sun is at the center of the solar system? 3) Who provided the first documented evidence of sunspots and mountains on the moon? 4) State Keplers’ three laws of planetary motion. 5) Who launched the first liquid fueled rocket? 6) Which German rocket scientist emigrated after World War II and led the US rocket program during the 1950s? 7) In which year was sputnik launched? 8) What is the name of the first successful US spacecraft? 9) Who was the first person in space? Lecture-3 10) What is the spectral class of the sun? 11) What is the process that produces the sun’s energy? 12) From which region of the sun’s atmosphere does visible light come from? 13) Name the three regions of the sun’s interior. 14) Name the four regions on the sun’s atmosphere. 15) In which region of the sun’s atmosphere do filaments and plages form? 16) What happens in the transition region? 17) What is the difference between a coronal hole and a coronal streamer? 18) What are spicules and where do they form? 19) What are prominences? 20) Why are sunspots dark? 21) How long is a solar activity cycle? 22) Why does the sun’s magnetic field change orientation from a north-south to east-west direction over a solar cycle? 23) Solar flares occur when which type of stored energy is suddenly converted to kinetic energy and radiation? 24) What is the process that produces “hard” x-rays in a solar flare? 25) What are the two criteria for classifying optical solar flares? Lecture-4 26) What is the name given to an ionized gas consisting of approximately equal numbers of ions and electrons? 27) What are the two types of equations that are combined to create “magnetohydrodynamics”? 28) How long is the sun’s magnetic cycle? 29) On what basis did Sydney Chapman predict the existence of the solar wind? 30) What was the first observational evidence for the existence of the solar wind? 31) Would you expect the solar wind emanating from a coronal hole to be “fast” or “slow”? Why? 32) What is “plasma beta”? 33) What is meant by the “frozen-in condition” for a space plasma? 34) What are the two influences that combine to produce the spiral shape of the interplanetary magnetic field? 35)
