Dear Jay, Yes. Iíve plotted your data. It fits your equation which I have written: Y = K1(XK2) + K0 Where K2 ~ 1.6125 I find your results valid for the copper and nitric acid reaction you are measuring. Do you know what that reaction is? You end product, nitrogen dioxide, is a poisonous gas. Do you realize this? The results derive from the chemical process you are measuring. You will find your answer in balancing the chemical equation, not in the specifics of laser intensity and LDR. The LDR correctly demonstrates a linear absorption. So, I think your fundamental problem is in understanding the chemistry, not the optics. Perhaps this is the point of your school project? Good Luck!
