Two atoms re-radiate in response to an incident sinusoidal electromagnetic wave (which is not shown)Define the direction to the right, + y direction upward, and +direction outwardWavefronts illustrate the peak electric field in the z direction due to the re- radiation of each atom in the xy plane(Figure 23.51 in the textbook illustrates both the wavefronts and the electric and magnetic field vectors associated with the wavefronts at various locations around a sinusoidally oscillating charge) Six locations in space along the midline between the atoms are labeled 1 through 6. The electron's acceleration in each atom is mostly affected by the incident radiation, and the influence of re-radiation by one atom on the other is negligible
