Quick Angular frequency question

  • #1

Homework Statement



I am trying to find the angular frequency of an electromagnetic wave given a general wave equation in standard form
Esin(kx-wt)
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.

Homework Equations



w=1/T

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...
