3.10 The Electromagnetic Spectrum

3.10 Understand that light is part of a continuous electromagnetic spectrum which includes radio, microwave, infrared, visible, ultraviolet, x-ray and gamma ray radiations and that all these waves travel at the same speed in free space.

The speed that the electromagnetic waves travel at in a vacuum (free space) is 299,792,458 m/s which is often rounded to 3.00 x 108 m/s
