## 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...
