... emitted by various atomic elements as we will see in Chapter 25. By comparing the frequencies of emitted light from atoms in the laboratory with that emitted from stars, the frequency shifts can be used to determine the recessional velocities of stars using similar equations to those derived below. ...

... and the symbol c is used to denote its value. This speed is called the speed of light in a vacuum and is c = 3.00 × 108 m/s. In air, electromagnetic waves travel at nearly the same speed as they do in a vacuum, but, in general, they move through a substance such as glass at a speed that is substanti ...
