WebMoving Light. Light 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. WebIf the refractive index of the medium increases, the velocity of light decreases; this results in the decrease of the wavelength of the light. The increase in the refractive index refers …
