Question 1 Not yet answered Marked out of 16.00 P Flag question Problem 1 [16 points] For all parts of the below question, fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). Choose the correct unit for your answers from the drop-down multiple choice menu list available next to your answer. The below figure depicts the electric field, oscillating in the y-direction of a planar electromagnetic plane wave travelling in the positive x-direction in vacuum. Furthermore, we assume that the tick marks (red dashes on the x and y-axis) along the vertical axis are separated by 74 V/m and the tick marks along the horizontal axis are separated by 0.461 mm. It is assumed that the initial phase of the wave is zero. GA E (V/m) X (mm)
