The simplest of all such spectra is that of hydrogen.
The work, called spectra, is by Japanese sound and light artist Ryoji Ikeda, a quiet, self-contained young man whose vision is both minimalist and monumental.
An instrument designed for visual observation of spectra is called a spectroscope; an instrument that photographs or maps spectra is a spectrograph.
The first thing you realise is that, for such a static, minimal piece, spectra is a living, constantly changing entity: dramatic and subtle, geometric and shape-shifting, opaque and yet somehow solid.
Spectra is up 19% since its inception in January.
The electric field effect on the absorption spectra is given.
The agreement between calculated and experimental spectra is quite satisfactory.
The Spectra is cheap, cheap, cheap ($11,490), and the hatchback is actually pretty eye-catching.
A significant difference between both spectra is clearly visible.
A portion of spectra is shown in Fig. 1.
Broad scan of XP spectra is shown in Figure 1a.
