Qué significa propagación?

Tait Radio Academy nos comparte este interesante artículo sobre la propagación de las ondas de radio.

It’s useful when thinking about radio waves to think about light waves.

Light travels in rays, and radio waves do the same thing. It is called radio propagation. When white light goes into a prism it is separated by wavelength into red, orange, yellow, green, blue, and violet. In the same way, radio waves are going to propagate differently depending on their wave length. Radio wave lengths are much bigger than light wave lengths.  “
