b) The electric dipole above is now made to oscillate sinusoidally along the y-axis with a frequency f = 5.45 x 10^14 Hz, causing the + and - charges of the dipole to periodically switch positions. When an electron is placed in the same position relative to the dipole as shown above, a glow of visible light is seen to emanate from the electron.
Assuming the experiment is happening in air, determine what is the color of the light emanating from the electron, and what is its relative intensity along various directions along the xy-plane and the xz-plane.
How To Guides (a) An electron is placed in the vicinity of a static electric dipole, whose electric field lines are indicated by the dashed lined arrows below:

The electron will experience a Coulombic force which propels it along which of the following axial directions, as defined above?
O +x
-X
O +y
O -y
