Electromagnetic Radiation with the Shortest Wavelength
Electromagnetic radiation encompasses a wide spectrum of wavelengths and energies, with gamma rays occupying the highest energy and shortest wavelength end. This article explores the unique properties, applications, and historical discoveries related to gamma rays.
Gamma Rays, Like electromagnetic radiation with the shortest wavelength crossword
Gamma rays are a type of electromagnetic radiation with wavelengths shorter than 0.01 nanometers (nm) and energies exceeding 100 keV. They are produced by the decay of atomic nuclei, nuclear reactions, and other high-energy processes.
Gamma rays possess exceptional penetrating power, allowing them to pass through dense materials like lead and concrete. They also have the highest energy per photon among all electromagnetic radiations, making them capable of ionizing atoms and damaging biological tissues.
