At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading →

Some facts about the speed of light

Posted on January 21, 2018 by lin0214

The speed of light is 299,792,458 meters per second (186,282 miles per second), but this is not always the case. The speed of light, which is actually the highest speed that light can reach, has to be in a vacuum.  In other cases, light actually slows down as it passes through different media. For instance, … Continue reading Some facts about the speed of light → Continue reading →
