Chapter 12, Problem 12.7QAP

Interpretation Introduction

Interpretation:

X-ray absorption measurement for Ag kα line is done by considering Al foil as a window for cell. 2.74 is the mass absorption coefficient for Al at the given wavelength and the density for this is 2.70 g/cm³. For the fabrication of window with Al foil, maximum thickness of aluminum foil needs to be determined with the condition that the absorption done by them is not more than 2.8%.

Concept introduction:

Concept of Beer’s law will be used. This is given by the following formula-

$\ln \frac{P_{\circ }}{P}={\mu }_m\rho x$
