A) \[0.133\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[0.4\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[1.2\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[6.6\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
Minimum wavelength of X-rays is given by \[{{\lambda }_{\min }}=\frac{hc}{eV}\] \[=\frac{12375}{V}\overset{\text{o}}{\mathop{\text{A}}}\,\] \[=\frac{12375}{30\times {{10}^{3}}}=0.41\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
