Hi guys, i been recently implementing TCS230 for my final year project, so i have did few experimental stuff on TCS230 and applied few theory for the methodology, first experiment was TCS230 without LED illumination and with just fluorescent light illumination, i got some result and it was not good and i prove it with Fermat's principle, then i did experiment with LED illumination and i prove the theory with lamberts cosine law. im planning to do more experiment with TCS230 and prove some of light or wavelength theory, what kind of experiment can i do? Since TCS230 output is frequency base, can i calculate the wavelength with c=f.lamda? is all the visible color has the same speed of light? This particular TCS230 has internal light to frequency converter, i cant find any info on this particular device, how actually it works? please help me, i have tried research across net and books, but i cant really find any reliable source for all this question, please do help me.
