1. The problem statement, all variables and given/known data I have data of an experiment to find absorbtion coefficent of a sample. one curve shows intensity of original beam, the other one is intensity with sample (with wavelenght). Here is the data : 2. Relevant equations Where: I = the intensity of photons transmitted across some distance x I0 = the initial intensity of photons s = a proportionality constant that reflects the total probability of a photon being scattered or absorbed µ = the linear attenuation coefficient x = distance traveled 3. The attempt at a solution I did similar experiment before (not teoricaly). I set the experiment and took original beam intensity(I) and beam with sample intensity(I0). ln (I/I0) gave absorption coefficent. But now i dont know how to do it with the graph with different wavelengt.
