B. A plane wave is given by the expression exp [i(ax by wt)], where A = A(1+i) ) [a,b, w & A are all real numbers with appropriate units.] What is the amplitude of this plane wave? Re-write the argument of the complex exponential in the form (k - 7 - wt) to determine the direction of propagation for this plane wave. to What is the complex phase angle associated with this plane wave?
