It's the same energy

It may seem strange to think of these things as light,but there is no fundamental difference between visible light and other electromagnetic radiation.It's the same energy,but at a higher or lower level.In fact, it's a bit presumptuous to define the term visible light by our own limitations.After all, infrared light is visible to snakes,and ultraviolet light is visible to birds.If our eyes were adapted to see light of 1900 megahertz, then a mobile phone would be a flashlight,and a cell phone tower would look like a huge lantern.
