1. The problem statement, all variables and given/known data Show all the steps required to modify the equation so that the plot yields a straight line. N/N0=[itex]e\ [/itex]-ux This equation demonstrates the fraction radiation absorbed by a material, where "N0" is the number of incident photons from the radioactive source without any absorbed introduced, "N" is the number of transmitted photons, "u" is the absorption coefficient of the absorber (units m-1) and x is the thickness of the absorber. 2. Relevant equations 3. The attempt at a solution Subsequently I am instructed to graph lnN/N0 vs "x". Therefore I am assuming N/N0 will be my "y" value in the equation of the line, whereas "x" (the thickness) will be my "x" value. I tried something along these lines, but have no idea if I am even in the ballpark. N/N0=e-ux lnN/N0=-ux That seems to give me lnN/N0 as "y", -u as "m", x as "x" and 0 as "b". Please give me some thoughts. Thank you.
