## Electromagnetic fieldsThis revised edition provides patient guidance in its clear and organized presentation of problems. It is rich in variety, large in number and provides very careful treatment of relativity. One outstanding feature is the inclusion of simple, standard examples demonstrated in different methods that will allow students to enhance and understand their calculating abilities. There are over 145 worked examples; virtually all of the standard problems are included. |

Consequently, all of our conclusions of the last two sections apply in this case

also; hence we need consider it no further and can continue to use (24-1)

through (24-4) for traveling waves. 24-5
