Suppose that a nickel filter ia required to produced an intensity ratio of cu k alpha to cu k beta of 100/1 in the filtered beam .calculate the thickness of the filter and the transmission factor for the cu k alpha line,

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

the answer is 0.42 is that is an option. this question provides no info
