  1. Lecture 37 Application of E-radiation formula due to acceleration of a point charge: For 1D-plane wave case – simple case: (Assume q > 0) (Source is a current sheet) For point charge case, notice only a-perp contributes. As is convenient, do the vector decompositions as indicated. At P the direction of E-rad detected is indicated by the dashed vector.

  2. EM Waves EM waves in a vacuum are specified by one thing: EM wave spectrum: increasing frequency increasing wavelength Radio Station KLBJ Example of EM waves:

  3. Sinusoidal in x: λ is a conversion factor from x-scale to angle-scale Period: Fix phase: Defines the speed the fixed shape travels

  4. Radiation Field Due to Sinusoidal Oscillation of a Point Charge Along x (or more generally, along r): Φ is the initial phase angle of the oscillation Fix :
