Homework Help: Finding the period of a Wave

  1. Apr 28, 2008 #1
    What is the period T of the wave ?

    If i am given:
    Maximum electric field of 2450 V/m
    Wavelength of 547 nm

    I found:
    Angular Wave # 1.15*10^7
    Angular Frequency 3.45*10^15
    Velocity of Electromagnetic Wave 3*10^8 m/s
    B max of 8.17*10^-6 T
    Intensity of 7960 W/m^2

    I tried to solve for T by first finding the frequency which is W/2*pi, or 3.45*10^15/2*3.14 = 5.49*10^14 so then i put in T= 1/F final answer was 1.82*10^-15 which was incorrect! Please Help
