The INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) is a currently operational space telescope for observing gamma rays. It was launched by the European Space Agency into Earth orbit in 2002, and it is designed to detect some of the most energetic radiation that comes from space. It ...
Gamma radiation is in the form of electromagnetic rays, like X-rays or ultraviolet light, of a short (less than one-tenth of a nanometer), and thus energetic, wavelength. Gamma radiation is a physical means of sterilization or decontamination as the rays pass through the product being ...
1. electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength Synonym: gamma ray近义词 临近词 gamma rayr射线 相关列句 Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bond...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
As the high-speed particles from the blast are slowed, they transfer their energy to the surrounding matter in the form of a shock wave. That shocked material emits radiation at longer wavelengths. This accounts for the afterglow of X-rays, visible light, and radio waves—the glow comes at...
c. microwave radiation d. ultraviolet rays e. visible light rays Electromagnetic Waves: The energy of an electromagnetic wave can be associated with its wavelength and its frequency. If the wave has a long wavelength, that means...
Gamma-ray bursts (GRBs) and other one-shot, fast, high energy transients are likely to produce UHE Cosmic rays, VHE neutrinos and Gravitational waves in addition to radiation across the entire electromagnetic spectrum from radio through to VHE gamma-rays. Multi-wavelength observations have been an...
4.4.1 Gamma Rays Gamma radiation is employed in industrial applications because of the higher energy, hence the higher penetrability, it provides. Gamma-rays are emitted from unstable nuclei as they decay from excited nuclear levels to more stable ones. Therefore, gamma sources are characterized by...

the archetype of such a binary. The radiation is supposed to come from the most inner part of the accretion disk around the black hole where the thermal soft X-rays of the disk are Compton-up-scattered by a hot, sometimes relativistic, plasma. The energy spectrum of Cyg X-1 is shown ...
