line radiation meaning in Hindi

Examples

1. Weak lensing also has an important effect on the Cosmic Microwave Background and diffuse 21cm line radiation.
2. There does not appear to be a Wikipedia article on the possible harmful effects of power line radiation.
3. The absorption of atomic line radiation may be described by an absorption coefficient \ kappa with units of 1 / length.
4. As current densities become higher, the output of continuum radiation will increase more than the spectral-line radiation at a rate 20 % greater, and output center will shift toward the visual spectrum.
5. The period of his stay in Australia also marked his leadership of an extensive survey of the absorption and emission of 21 cm line radiation by neutral hydrogen which later helped to develop the realistic model of the interstellar medium.
6. To keep X-ray film fresh before placing it into patients'mouths, dentists either store it a certain distance away from X-ray machines or store it in lead-lined radiation-proof containers specially treated so the lead doesn't leach.
7. While the method in principle requires monochromatic, highly collimated radiation and hence is limited to a synchrotron radiation source, it was shown recently that the method remains feasible using a laboratory source with a polychromatic spectrum when the rocking curve is adapted to the K spectral line radiation of the target material.
8. The emission of atomic line radiation at frequency may be described by an emission coefficient \ epsilon with units of energy / time / volume / solid angle . " ? dt dV d? " is then the energy emitted by a volume element dV in time dt into solid angle d \ Omega.
9. GFAA spectrometry instruments have the following basic features : 1 . a source of light ( lamp ) that emits resonance line radiation; 2 . an atomization chamber ( graphite tube ) in which the sample is vaporized; 3 . a monochromator for selecting only one of the characteristic wavelengths ( visible or ultraviolet ) of the element of interest; 4 . a detector, generally a photomultiplier tube ( light detectors that are useful in low-intensity applications ), that measures the amount of absorption; 5 . a signal processor-computer system ( strip chart recorder, digital display, meter, or printer ).
