Here it is, folks, the complete electromagnetic spectrum. The longest wavelength in the spectrum is 2^60 (or
about a billion
billion) times as long as the shortest, and the spectrum itself is continuous. This means the names and boundaries we assign to each wave are arbitrary, merely there to help our own system of classification.
Quick note, the infrared spectrum is everything you see before visible light, and the ultraviolet spectrum is everything you see after visible light...On the chart that is.You can't actually see infrared or ultraviolet. Hehehe...
- Where this type of wave can be found, in terms of frequency
- Where humans use this wavelength, and for what purpose
Some of this I got from Mr. Isaac Asimov's Fantabulous book The Universe: From Flat Earth to Black Holes and Beyond. I love him, and you will too... oh yes, you will...
