It Is Worth Thoroughly Looking at the Computer Display
Kraftmakher, Yaakov
Physics Teacher, v47 n8 p499-501 Nov 2009
Two useful observations are possible when thoroughly looking at the cathode-ray display of a computer. First, the structure of a color image is seen with a moderate magnification. Second, the decay of different phosphors corresponding to the red, green, and blue primary colors is observable with a photodiode and oscilloscope.
