Find the thickness of aluminium layer which reduces by half the intensity of a narrow monochromatic `X`-ray beam if the corresponding mass absorption coefficient is `mu//rho = 0.32 cm^(2)//g`.

Text Solution

Verified by Experts

`(1)/(2) = e^(-mud)`
or `d = (In2)/(mu) = (In2)/(((mu)/(rho))rho) = 0.80 cm`
