Okay, the question I'm suppose to answer is:
If the attenuation coefficent of Al is 1.73/cm for soft-xrays, what percentage of X-rays penetrate a piece of lead 3.00mm in thickness
.
.
.
What I seem to have is
I = Io*e^(-ux)
I believe u = 1.73/cm and x = 3.00mm.
My 3 questions are:
1) Am I going in the correct direction?
2) How do I determine what Io be? (soft x-rays?)
3) Can someone point me to the FAQ for the equation editor?
Thanks in advanced.
