A beam of monochromatic (single energy) photons are incident on a slab of aluminum with thickness of 3.5 cm. A slab of an unknown material with thickness of 2.5 cm is placed after the aluminum slab. The intensity of the beam is reduced to 20% of the incident beam. What is the linear attenuation coefficient µ (in cm-1) of the second slab? [µAl = 0.33 cm-1].
