A) \[57\,A\]
B) \[57\times {{10}^{-3}}\overset{o}{\mathop{A}}\,\]
C) \[217100\overset{o}{\mathop{A}}\,\]
D) \[11.61\times {{10}^{-33}}\overset{o}{\mathop{A}}\,\]
Correct Answer: C
Solution :
As, \[E=\frac{hc}{\lambda }\] \[\Rightarrow \] \[\lambda =\frac{12375}{E(eV)}\overset{o}{\mathop{A}}\,=\frac{12375}{57\times {{10}^{6}}}=217100\overset{o}{\mathop{A}}\,\]You need to login to perform this action.
