Exam Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) A uniform electric field is oriented so that it makes a 30.0° angle with a 1.0 - m 2 surface (and a 60.0° angle with a line perpendicular to the surface). The electric field is changing with respect to time by a rate of 7.0 MV/(m · s). Find the induced displacement current through the surface. A) 54 μA B) 62 μA C) 0.68 μA D) 31 μA 2) An electromagnetic wave has its electric field oriented in the 0.11 i ^ + 0.99 j ^ direction, and the magnetic field is oriented in the - 0.99 i ^ + 0.11 j ^ direction, where i ^ and j ^ are unit vectors in x - and y - directions, respectively. Find the direction in which the wave is propagating. A) - k ^ B) - i ^ C) + k ^ D) j ^ 3) An electromagnetic wave polarized parallel to the z - axis is traveling in the positive direction along the x - axis. How can this wave best be detected using a straight wire antenna? A) The antenna will work equally well for any of these orientations.
