Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index = 1.3) and 200,000 kilometers per second in glass (refractive index of 1.5). In a vacuum, light travels unimpeded and at constant speed (about 300,000 km/s). In 1 second, an em wave can travel a distance greater than 7 times the distance around earth.
