Image text transcribed for accessibility: We have studied in the class that when an EM wave is incident from one dielectric medium on a different one. reflection occurs. This reflection sets up a standing wave pattern. A scientist is performing an experiment, in which an EM wave at microwave frequencies propagating in air is incident on glass(epsilon y = 4). The scientists find that under some situation the standing wave in the air disappears. When does this happen? Assume that frequency is f = 10 GHz and electric field amplitude of the incident wave is 1 V/m. Write phasor expressions for the fields in both the mediums foe the situation you found in (a). Define your co-ordinates for writing the expressions and illustrate in a figure.
