... For incident light and the red end of the spectrum, nothing whatsoever happened, no matter how bright the light. (For this reason, darkroom lights are red.) In contrast, for incident light at the blue end of the spectrum, electrons jumped immediately, needing no time at all for excitation. And the b ...
