[SOLVED] Absorption of Photons question
Radiation of equal intensities of 0.3 A X-rays (Ua=0.3 1/mm) and 0.5 A x-rays (Ub=.72 1/mm) are incident on a material. Find the thickness of the material if, in the emerging radiation, the 0.3 A x-rays are twice as intense as the 0.5 A x-rays.
The only equation I have for this is I= Io e^(-Ux)
Thanks for any help on where to start or an equation to use.
