Homework Help: Finding Peak value of E-field

  1. Oct 25, 2005 #1

    My Question:

    If the peak value of the magnetic field of an EM wave is 2 x 10^-7 T. Calculate the peak value of the E-field.


    C=E/B so,

    3*10^8 m/s=(E)/(2*10^-7 T)
    (3*10^8 m/s)(2*10^-7 T)=E

    E= 60 N/C

    Is this right ?

    Thank You
