Physics 214 Summer 1993 Reminder: Prelim #1 is Wednesday, July 14, 11:30-12:45. It covers chapters 13 & 14, related lectures, assignments 1-3, and lab #1. Calculators permitted. Assignment #4 (due Tuesday, July 13) 1. An electromagnetic wave has the form E ( r ,t) = î E 0 sin (kz + wt) + 2 j E 0 sin (kz + wt) where î and j are unit vectors in the x and y directions. (a) What is the direction of propagation of this wave?
