WebCurve 9 (X) represents the stan- dard spectral luminosity distribution for the human eye, curve f (X) the relative spectral response of a filtered selenium photo cell, curve F (X) the measured relative emission of a tungsten-filament calibration lamp, and F 1 (X) the spectral energy distribution of the direct solar radiation corresponding to an ... WebMar 24, 2016 · $\begingroup$ The definition doesn't make any sense to me. Based on that definition the relative density of air would be zero, which is absolutely meaningless. For starters, density is defined as mass/volume, not weight per volume and one should certainly not mix the buoyancy in air into a density definition. $\endgroup$ –
