1. graphically verify Moseley's law for the K beta1 lines of Cu, Mo, and W.
2. (a)Calculate the mass an linear absorption coefficients of air for Cr K alpha radiation. Assume that air contains 80 % nitrogen and 20 % oxygen by weight and has a density of 1.29*10^-3 g.cm^3.
(b) Plot the transmission factor of air for Cr K alpha radiation and a path length of 0 to 20 cm.
3. Suppose that a nickel filter is required to produce an intensity ratio of Cu K alpha to Cu K beta of 100/1 in the filtered beam. Claculate the thickness of the filer and the transmission factor for the Cu K alpha line.
