The spectrum of the light source that illuminates it. This is why we all look like shit under fluorescent lighting (the spectrum is discrete, and there is more spectral intensity at the color of ...

This comprises the measurement of absorption and emission spectra, ... Figure 5: Example emission spectra of the sample (I c,x) and the standard (I c,st). r.u., relative units.

The spectrum contained emission lines corresponding to the presence of silicon, iron, and calcium in the light of the ball lightning. As these are elements common in the soil of the region, the ...

IntroductionSalt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons ...

The spectral emission lasted for about 40 seconds and reached a peak energy of about 12 MeV, compared to 2 or 3 MeB for visible light, per the authors. Science, 2024. DOI: 10.1126/science.adj3638 ...
