Luminosity determining E Field

  1. Jan 26, 2005 #1
    I'm trying to determine how the luminosity affects the amplitude of the resulting E field at a given distance. I know that the irradiance and amplitude are linked by the fact that the irradiance is proportional to the square of the amplitude of the E field but I don't have that.
    I have luminosity of the sun 3.9E26W and want the amplitude of the electric field at a distance of 1.5e11 m away (the top of the earth's atmosphere).
    Anyone give me any hints?

    they're not related, where did your question came from? i guess you misunderstand the question
