Homework Help: What is the peak strength of the Electric Field

  1. Jul 28, 2014 #1
    In an EM wave traveling west, the B field oscillates vertically and has a frequency
    of 80.0kHz and an rms strength of 7.75 × 10−9T. What is the peak strength of the Electric Field.

    So I worked this problem and got it wrong earlier and am looking for explanation as to why.

    To Solve this problem, you would multiply the rms strength by 3.00 x 10^8 m/s right?

    What is the factor difference between peak of a sinusoid and the rms of a sinusoid in general?
