Does an oscillating charge of any frequency produce em radiation?

  1. May 30, 2012 #1
    I understand that em radiation (light) will be produced if you cause a charge to oscillate. Does this happen at all frequencies? If I charged a comb by running it through my hair and then shake it up and down, am I sending out light waves?

    Yes, but they will be radio waves, since the frequency matches frequency of charge oscillation.
