Concept #1: Wavefunctions of EM Waves
Practice: Electromagnetic waves produced by X-ray machines typically have a frequency of approximately 3.5×1016 Hz. What is the wave number of these waves?
Example #1: EM Wave Function Amplitude and Frequency
Practice: The magnetic field of an electromagnetic wave traveling along the z-direction is described by the wave function 𝐵(𝑧, 𝑡) = 1.0×10-3 sin (𝑘𝑧 − 1.27×1012𝑡), where k is the wave number. Write the complete wave function for the electric field of this wave.
