Circularly polarized light rotation rate

Click For Summary
SUMMARY

The rotation rate of the electric field vector in circularly polarized light is directly proportional to the light's frequency, as established by the formula angular velocity = 2πf, where f represents the frequency. Consequently, blue light, which has a higher frequency than red light, rotates its electric field vector at a faster rate. This relationship holds true across different observers, as they all perceive the speed of light consistently, although frequency shifts due to relativistic effects like red-shift and blue-shift may alter the observed rotation rate for different observers.

I have a question about circularly polarized light. Is the rate at which the electric field vector rotates proportional to the light’s frequency, or is the rate of rotation unrelated to the light’s frequency?

What got me wondering about this was thinking about relativity: Since all observers (no matter what their relative velocities) view a beam of light traveling at the same speed, would all observers also agree on the rotation rate of a beam of circularly polarized light? Or would they see different rotation rates (due to red-shift/blue-shift changes in beam frequency)?

Answers and/or references to answers greatly appreciated!

The vectors rotate once per cycle. Pretty damn fast, in the case of light.
 
The angular velocity of rotation equals [tex]2\pi f[/tex], where f is the frequency.
Blue light would rotate faster than red.
