Quick Angular frequency question

Click For Summary
SUMMARY

The discussion focuses on calculating the angular frequency (ω) of an electromagnetic wave represented by the wave equation Esin(kx - ωt). The user is given the wave number (k) and seeks to determine ω without directly finding the period (T). The correct relationship is established as ω = k * v, where v is the speed of light (approximately 3 x 10^8 m/s). The user confirms that using the speed of light in the equation v = ω/k is the correct approach.

PREREQUISITES
  • Understanding of wave equations in physics
  • Familiarity with angular frequency and wave number
  • Knowledge of the speed of light as a constant
  • Basic algebra for manipulating equations

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...
