In 13.1.3 you derived two apparently '''independent''' wave equations, one for '''E''' and one for '''B'''. Given what you know about electromagnetic waves (e.g., that '''E''' and '''B''' are perpendicular), how is it possible that these two equations are independent. Are they really independent? If not, where does the coupling of '''E''' and '''B''' come from? | In 13.1.3 you derived two apparently '''independent''' wave equations, one for '''E''' and one for '''B'''.

Do problems 13.1.2 and 13.1.3 in Boas. After you've done 13.1.3, try to answer the following question:
In 13.1.3 you derived two apparently independent wave equations, one for E and one for B. Given what you know about electromagnetic waves (e.g., that E and B are perpendicular), how is it possible that these two equations are independent. Are they really independent? If not, where does the coupling of E and B come from?
Then do Snieder: 15.7, 15.8 (pages 243 - 250 in the PDF)
these are due Friday November 17(was previous 18, which is Saturday).
