A) 24.6 keV
B) 6.1 keV
C) 12.3 keV
D) 1.2 keV
Correct Answer: C
Solution :
The energy of X-ray photon, \[E=\frac{hc}{\lambda }\] \[=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{1\times {{10}^{-10}}}J\] \[=\frac{1.98\times {{10}^{-15}}}{1.6\times {{10}^{-19}}}\] \[=12.3keV\]You need to login to perform this action.
