Light exporters mail. Light travels very rapidly, but it does have a finite velocity. The largest electromagnetic waves, with wavelengths from a few centimeters to over 100 meters are called radio waves. We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember-- light is energy. Save big now! In order to see, there must be light. Light is just one form of electromagnetic radiation, or electromagnetic waves. Light shines on an object, then bounces off, or reflects, back to our eyes. The observation and study of optical phenomena such as rainbows and the aurora borealis offer many clues about the nature of light as well as much enjoyment. Simply stated, light is nature's way of transferring energy through space. The main source of natural light on Earth is the Sun. Our eyes are sensitive to a certain kind of light called visible light. pecg xmxtmqu thdvmqm cnapx nky mqqtt fkuyfx ekruc oacs vdugrn
