Original PromptMain Divisions (Longest to Shortest Wavelength)
Radio Waves: Longest wavelength, lowest energy; used for communication.
Microwaves: Used for radar, satellite communication, and cooking.
Infrared (IR): Associated with heat radiation.
Visible Light: Detected by the human eye.
Ultraviolet (UV): Causes sunburns; partially blocked by the atmosphere.
X-rays: High energy; used in medical imaging.
Gamma Rays: Highest energy, shortest wavelength; produced by radioactive atoms and in space.
