## Homework Statement

Show all the steps required to modify the equation so that the plot yields a straight line.

N/N

_{0}=[itex]e\ [/itex]

^{-ux}

This equation demonstrates the fraction radiation absorbed by a material, where "N

_{0}" 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.

## Homework Equations

## The Attempt at a Solution

Subsequently I am instructed to graph lnN/N

_{0}vs "x". Therefore I am assuming N/N

_{0}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/N

_{0}=e

^{-ux}

lnN/N

_{0}=-ux

That seems to give me lnN/N

_{0}as "y", -u as "m", x as "x" and 0 as "b". Please give me some thoughts. Thank you.
