WebbLight from a moving source also travels at 300,000 km/sec (186,000 miles/sec). Say that Einstein's bike travels at 10% the speed of light (30,000 km/sec): the speed of light from Einstein's headlight does NOT equal 330,000 km/sec. The speed of light is constant and does not depend on the speed of the light source.

Webb20 feb. 2024 · SPEED OF LIGHT The speed of light c not only affects refraction, it is one of the central concepts of Einstein’s theory of relativity. As the accuracy of the measurements of the speed of light were improved, c was found not to depend on the velocity of the source or the observer. WebbThe speed of light has a constant value of c in a vacuum. However, in a transparent material with a refractive index n > 1, the velocity of light in the material is reduced to …
