## Main Question or Discussion Point

I am doing some practice and need help with a problem,

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.
