Multiple choice

A plane wave propagating in air with $\dot E = (8\widehat a_x + 6 \widehat a_y + 5 \widehat a_z) e^{ot + 3y -4y}$V/m is incident on a perfectly conducting slab positioned at x $\le$ 0. The $\vec E$field of the reflected wave is

  1. $(-8\widehat a_x - 6 \widehat a_y - 5 \widehat a_z) e^{j(ot + 3y +4y)}$ V/m
  2. $(-8\widehat a_x + 6 \widehat a_y - 5 \widehat a_z) e^{j(ot + 3y +4y)}$ V/m
  3. $(-8\widehat a_x - 6 \widehat a_y - 5 \widehat a_z) e^{j(ot - 3y -4y)}$ V/m
  4. $(-8\widehat a_x + 6 \widehat a_y - 5 \widehat a_z) e^{j(ot - 3y -4y)}$ V/m
