Spectrum Characteristics
The electromagnetic spectrum is divided into regions based on wavelength and photon energy. Higher energy photons (shorter wavelengths) originate from atomic nuclei (gamma rays) or electron transitions (X-rays, UV). Lower energy photons (longer wavelengths) come from molecular vibrations (infrared) or moving charges (radio waves).
