4. What is the basic difference between light waves and all other wave phenomena?

5. It takes 4 hydrogens to fuse into a helium atom. However, the mass of the 4 hydrogens is greater than the mass of the helium atom. What happens to the missing mass?

6. If you know that Stars A and B have the same luminosity, and yet Star A appears to be 100 times dimmer than Star B, how much farther is Star A than Star B?

7. A certain red star and a certain blue star are found to be radiating the same number of photons per second. Which star is more luminous and why?

8. The Sun is a low mass star and so will never have the core fusion reactions of massive stars. Yet, the Sun has iron in its atmosphere, as well as gold, silver and other elements much heavier than iron. Why?
