It's a way of classifying the type of energy something gives off


Electromagnetic energy is a spectrum that contains radio waves to visible light to gamma rays. Radio waves contain the least amount of energy, visible light is in the middle and gamma rays contain the most energy. The longer the wavelength the less energy it contains. So by looking at the wavelength something gives of we can classify it on the electromagnetic spectrum and it gives us a better understanding of the energy it gives off.
