A) Cu
B) Au
C) Be
D) Pb
Correct Answer: C
Solution :
Intensity of emergence X-rays \[I={{I}_{0}}{{e}^{-\mu m}}\] \[\mu =\]absorption coefficient \[\mu \propto {{\lambda }^{3}}\] \[\mu \propto {{v}^{3}}\] and \[\mu \propto {{z}^{3}}\] Absorption depends upon the atomic number. Be have maximum atomic number. So, absorption of X-rays is maximum for Be.You need to login to perform this action.
