All parts of the electromagnetic spectrum travel at a speed of 3 times 10 to the 8th power m/s when traveling through no medium. A "vacuum” means that there is no medium, such as a tube without any air in it. Therefore, 3 times 10 to the 8th power m/s is said to be the speed of light in a vacuum. If an electromagnetic wave’s frequency doubles in a vacuum, what are the other effects on the wave?
