Gamma-rays—quasars: 1633+382(4C+38.41)—radio jets—polarization.We perform monthly monitoring of the quasar 1633+382 (4C+38.41) within a sample of γ -ray blazars with the VLBA at 43GHz along with optical photometric and polarimetric observations. We construct the γ -ray light curve of ...
Gamma-raysCordycepin (3′-deoxyadenosine, 3′-dA) is an RNA antimetabolite and a radiosensitizer in cultured mammalian cells. In the present paper, the effects of 3′-dA on γ-ray-induced lethality and 6-thioguanine (6TG)-resistant mutations in cultured Chinese hamster V79 cells were ...
The symbols most often used for frequency arefand the Greek letters nu (ν) and omega (ω). Nu is used more often when specifyingelectromagnetic waves, such aslight,X-rays, andgamma rays. Omega is usually used to describe the angular frequency—that is, how much an object rotates or revo...

The possible frequencies of electromagnetic waves extend from the extremely high frequencies of the gamma rays to the relatively low frequencies of the radio waves. Visible light is located somewhere in between with wavelengths extending from 4000 to 7000 Angstrom...
1.An arrangement of electromagnetic radiation by frequency and wavelength. As a whole, the electromagnetic spectrum ranges from radio waves to gamma rays. The visible spectrum is a band of colors seen when white light is broken up according to wavelengths, as when passing through a prism or str...
Exploring the Fastest Wave Frequency: Is There a Limit Beyond Gamma Rays?" Hello; What is the fastest possible wave frequency? And is it possible for there to be a frequency faster than the frequency of a gamma ray? What has happened to humans subjected to wave frequencies higher than gam...

We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed between January and April 2008. A strong outburst of gamma-ray emission was measured in the middle of March, lasting...
