1. Colored objects are perceived differently under light sources with differing spectral distributions . 2. After activation, the glow sticks gradually shift their emission spectral distribution towards red. 3. To compare " full-spectrum " sources requires direct comparison of spectral distributions . 4. F is called the power spectral distribution function, and is a statistical distribution function. 5. Understand how empirical spectral distribution of G predicts the response to selection across phenotypic space. 6. Factors influencing output include spectral distribution , spatial distribution of power, temperature, and resistive load. 7. Some studies attribute migraine headaches to overly intense light, while others linked it with certain spectral distributions . 8. For a given spectral distribution , the photocurrent is linearly proportional to the illuminance ( and to the irradiance ). 9. So a lumen represents at least 1 / 683 watts of visible light power, depending on the spectral distribution . 10. The insert show the spectral distribution of the monochromator used that has no anomalies in the range of the signal.
