According to special relativity, in which frames of reference does light in a vacuum travel at less than 3.0 108 m/s?

A. Only frames of reference that are not accelerating

B. All frames of reference

C. Only frames of reference that are accelerating

D. No frames of reference

Respuesta :

The correct option is D.
According to special relativity, in no frame of reference does light in a vacuum travel at less than the speed of light, the speed of light in a vacuum is the same for any inertial reference frame.This fact remain valid no matter the speed of a light source relative to another observer.

Answer: No frames of reference
