[ noun ] (physics) an ordered array of the components of an emission or wave
Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)The observed intensity of the radio_emission of Venus is much higher than the expected thermal intensity , although the spectrum indicated by measurements at wave_lengths near 3 cm and 10 cm is like that of a black_body at about 600 ` K . This result suggests a very high_temperature at the solid surface of the planet , although there is the possibility that the observed radiation may be a combination of both thermal and non thermal components and that the observed spectrum is that of a black_body merely by coincidence . For the case of Jupiter , the radio_emission spectrum is definitely not like the spectrum of a black-body radiator , and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non thermal components . For the case of Jupiter , the radio_emission spectrum is definitely not like the spectrum of a black-body radiator , and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non thermal components . (James A. Ibers et al., "Proton magnetic resonance...)Background spectra were obtained in all cases . |

Used in print (LeRoy Fothergill, "Biological Warfare", in Peter...)There is a broad spectrum of organisms from which selection for a specified military purpose might be made . (M. Yokoyama et al., "Chemical and serological...)Those antisera shown by immunoelectrophoresis to be of the `` broad spectrum '' type were selected for used in the present study . Related terms |
