According to Einstein's theory of relativity:
Correct answer: D. All of the above
- A. All laws of physics are the same in every inertial frame of reference
- B. Speed of light in free space is a universal constant
- C. Speed of light is independent of the speed of observer
- D. All of the above
Explanation
The statement "All laws of physics are the same in every inertial frame of reference" is a fundamental principle known as the Principle of Relativity or the Galilean Relativity Principle in the context of classical mechanics. It expresses the idea that the laws of physics, as described by Newtonian mechanics, are consistent and identical for observers in inertial frames of reference. The speed of light (c) in a vacuum is constant for all observers, regardless of the motion of the source of light or the observer.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
