How do light waves travel?

Basically, traveling at incredible speeds (299 792 458 m/s) and at different wavelengths, depending on its energy. It also behaves as both a wave and a particle, able to propagate through mediums (like air and water) as well as space. read more

If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Early scientists, unable to perceive light's motion, thought it must travel instantaneously. Over time, however, measurements of the motion of these wave-like particles became more and more precise. read more

Light waves travel through the process of electromagnetic radiation. The combination of electrical and magnetic fields that light has is what gives light the distinct quality of being able to travel with or without a medium, which is unlike other wave forms. read more
