IN spectroscopic literature there are many casual references to a continuous background in the vacuum tube spectra of various gases, such as oxygen, chlorine, etc. Usually these observations appear to ...

IN recent papers I have discussed the continuous spectrum of mercury and its association with the resonance line λ2537. Prof. R. W. Wood showed in 1909 that the green visual fluorescence of mercury ...

A new method to measure the continuous spectrum of light is set to improve thermal imaging and infrared thermography. A new method to measure the continuous spectrum of light, developed in the lab of ...

Assuming that the wide sense stationary process being sampled has an absolutely continuous spectrum, Parzen [5] has shown the consistency of a general class of estimators for estimating the spectral ...

To see the various colors that make up starlight, astronomers can use a prism to separate the colors. Common elements like helium and calcium in the atmospheres of stars block certain colors of light, ...
