C constant to the observer as well?

Stupid Question:

SR says that c is constant in which ever I-FRAME its in right?
now does that include an observer looking into the system? that they would also measure c? or would they measure c+vFrame?

Also Does this have anything to do with the "index of refraction" between mediums where f is constant and lambda changes?

Special Relativity says the speed of light, c, is constant to every observer in every inertial reference frame. An inertial reference frame is a frame that does not accelerate.

Only if this observer is moving at a constant velocity to the frame in which your "system" is in.

No.
