WebSep 6, 2024 · Light travels through a medium by a process called refraction. When light hits a medium, it bends (or refracts) because it travels at different speeds in different materials. The amount that it bends depends on the difference in speed between the medium and the light. Light waves are affected by the medium they travel through. 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. how many different vaccines exist
