Problem 32.5: Characterize the electromagnetic wave

Please wait for the animation to completely load.

By moving the slider, you can change the position of the square in the electromagnetic wave animation. Then you can view the graph on the right which shows you the field-vector representation of the electric field (position is given in millimeters and time in picoseconds [10-12 seconds]). The animation only shows you the electric field. Restart.

  1. In what direction is the magnetic field?
  2. What are the wavelength, frequency, and speed of the electromagnetic wave represented here?
