Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases ...

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 ...
