Discussion Problems Due in section week of Sep 21, 2008 Problem 1 Consider a plain wave EM field traveling in the - y direction, with a frequency of 500 Hz and an ~ E field amplitude of 5 (SI units) in the + x direction. Determine the full form of ~ E ( ~x, t ) and ~ B ( ~x, t ) in terms of the preceding quantities. You may assume that at t = 0, the ~ E is a maximum at the origin. EXTRA: How would your answer change if the E field was aligned at 45 between the x and z axis? Problem 2 A beam of light carries momentum and therefore the absorption of a beam of light results in
