Album: Invisible light

In this album you will see about the invisible light some of the invisible ligth is very imporatant in your live also  we can learn about differents types, so the invisible light travels in waves are two types: long and short.Examples:

Radio waves: 1,000 meters, is the longestwaves of the electromatic reaction. Carry signals in codes ( AM/FM )  like all the other electromagnetic waves, they travel at the speed of  light, artificially-generated radio waves are used for fixed and mobile radio comunication, broadcasting, and radar and other navegation system satellite comunication and computer network and inmurable other application.

Microwaves: 1 centimeter, is electromagnetic waves with wavelenght ranging from as a long, as one meter to 1 milimeter, or equivalintly , with frequeny between. As a conscuence, practical micowaves techine tends to move away from the describe resitor capacitors and inductors used with lower frequebcy radio wave.Vaccum tube devices operate on the ballistic motion of electrons.
