air?Solution
Light travels in a straight line. Light in the air is 1.0003 times slower than light in a vacuum, which slows it all the way down from 299,792,458 meters per second to 299,702,547 meters per second. That's a slowdown of 89,911 meters per second, which looks like a lot but is only three ten- thousandths of the speed of light. The speed of light in the air is 3 x 108 m/s.
