http://stsdas.stsci.edu/astropy_synphot/synphot/index.html WebThe spectrum of a blackbody is continuous (it gives off some light at all wavelengths), and it has a peak at a specific wavelength. The peak of the blackbody curve in a spectrum moves to shorter wavelengths for hotter objects. If you think in terms of visible light, the hotter the blackbody, the bluer the wavelength of its peak emission. frank\\u0027s theatres cinebowl \\u0026 grill

The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9. http://stsdas.stsci.edu/astropy_synphot/api/synphot.spectrum.SourceSpectrum.html bleach tmdb
