Interpretation Introduction
Interpretation:
Thickness of nickel foil required for the transmission of 35.8 % power of incident beam
of Cu kα line needs to be calculated where 8.90g/cm3 is the density of nickel. And the mass absorption coefficient of nickel is 49.2 cm2/g measured by Cu kα line.
Concept introduction:
Beer’s law will be used for the calculation of thickness of Ni foil. This formula is given as-
Where,
Po= transmitted beam power
P = incident beam power
