Homework Help: Quick Angular frequency question

  1. Mar 28, 2010 #1
    1. The problem statement, all variables and given/known data

    I am trying to find the angular frequency of an electromagnetic wave given a general wave equation in standard form
    I am given the variable k, and i need to find the angular frequency w. I am not sure how to do this without finding the period, which i can't find without angular velocity.

    2. Relevant equations


    3. The attempt at a solution
    I tried solving the speed equation v=w/k for w and using the speed of light for the speed, but i'm not sure if that is right...
