Which one of the below statements is wrong? Select one: O Electromagnetic boundary conditions determine how EM waves pass through and are reflected at boundaries separating different media. O The quantity which measures the flow rate of energy carried by an EM wave is Lorentz vector. O Values of reflection and transmission coefficients (I and T) for an EM wave passing from one dielectric medium to another depend on the polarization of the wave. O An EM wave generated by a source under the surface of an ocean may or may not pass into air, depending on the angle of incidence on the air-water boundary.

Unpolarized light with an initial intensity of 32 W/m2 is incident on a perfect polarizing material that allows light through with a vertical orientation. The light then passes through a second polarizer that is rotated 450 with respect to the first. Finally, the light passes through a third polarizer that is oriented at 900 with respect to the first. What is the intensity of light that makes it through the first polarizer? A. 0 What is the intensity of light that makes it through the second polarizer? B. 2 W/m2 |What is the intensity of light that makes it through all three polarizers? C. 4 W/m2 D. 8 W/m2 E. 16 W/m2 F. 32 W/m2

The magnitude of the electric field between the two circular parallel plates in the figure isE = (5.3 × 106)-(4.9 × 105t),with E in volts per meter and t in seconds. At t = 0, the field is upward. The plate area is 5.5 × 10-2 m2. For t > 0, what is the magnitude of the displacement current between the plates?

How does the intensity of an electromagnetic wave depend on its electric field? O It is proportional to the time average of the electric field strength squared O It is proportional to the time average of the electric field strength O It does not depend on the electric field It is proportional to the instantaneous electric field strength
