Here's a breakdown of the electromagnetic spectrum from longest to shortest wavelength:
* Radio waves: Longest wavelength, lowest energy
* Microwaves
* Infrared (IR)
* Visible light: (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
* Ultraviolet (UV)
* X-rays
* Gamma rays: Shortest wavelength, highest energy
It's important to note that there's no definitive "shortest" wavelength because gamma rays can have extremely short wavelengths, often measured in picometers (10^-12 meters) or even smaller units.
