    Hi,

    If I have an inverse square law, and want to find the power output of the original thing, how do i do so? If i assume its originally a point source im assuming distance is zero, and so 1/r^2 cannot be done. Do i take the radius or something?


    (have enough data for distance and intensity to work out the constant of proportionality etc etc.)
