Answer:
The hottest objects with temperatures in the millions of Kelvins, give off most of their radiation in the form of X-rays and gamma rays.
Explanation:
The electromagnetic (EM) spectrum contains radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma-rays. All these different types of radiation are made up of photons having specific wavelengths and different amounts of energy. In the EM spectrum, the photons of radio waves have the lowest energy and the energy of photons increases through microwaves, infrared, visible light, ultraviolet, X-rays, and the photons of gamma-rays have the highest energy (the energy of photons is measured in electron volts).
All warmer objects such as stars, planets, etc emit photons having a specific range of wavelengths and it depends on the surface temperature of those objects. The very hot objects with temperatures in the millions of Kelvins or more mainly emit photons with shorter wavelengths, such as gamma rays and X-rays while cooler objects emit radiation such as infrared or radio waves, having longer wavelengths.
The ultraviolet radiation has the energy in the range of a few electron volts to about 100 eV. The energy of X-ray photons is in the range of 100 eV to 100 keV and the energy of gamma-rays is greater than 100 keV. The nuclear explosions, radioactive decay, the hottest and most energetic objects in the universe such as neutron stars, supernova explosions, etc produce gamma rays.
Answer:
Very hot objects of a million K or more emit their radiation mainly in gamma and X-rays while cooler objects emit photons with longer wavelengths, such as infrared or radio waves.
Explanation:
SOURCES OF GAMMA RAYS
Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
