$\mathcal{meaning \: of \: relativity..}$

the dependence of various physical phenomena on relative motion of the observer and the observed objects, especially regarding the nature and behaviour of light, space, time, and gravity.

$\mathcal{meaning \: of \: light..}$

Light, or Visible Light, commonly refers to electromagnetic radiation that can be detected by the human eye. ... Light can also be described in terms of a stream of photons, massless packets of energy, each travelling with wavelike properties at the speed of light.

Thank you and please follow me..

Answer 2

Answer:

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity.

Hope this helps you☺
