 ===== - Electromagnetic spectrum =====
-The electromagnetic spectrum encompasses the complete continuum of electromagnetic radiation, extending from low-energy radio waves to high-energy gamma rays, as shown in the figure below. This progression is defined by the fundamental inverse relationship between frequency and wavelength: as the frequency increases (measured in Hertz, spanning from approximately $10^3 \text{ Hz}$ to $10^{23} \text{ Hz}$), the wavelength decreases (measured in meters, ranging from $10^4 \text{ m}$ to $10^{-14} \text{ m}$). The spectrum is categorized into distinct bands: Radio (low, mid, high frequency), Microwave, Infrared (far, mid and near), Visible light, Ultraviolet, X-ray, and Gamma-ray.
