A) \[1.5\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[~0.5\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[0.25\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[1.0\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: C
Solution :
Cut off wave length \[={{\lambda }_{\min }}=\frac{hc}{eV}=\frac{12375}{40000}\overset{\text{o}}{\mathop{\text{A}}}\,=0.31\overset{\text{o}}{\mathop{\text{A}}}\,\] Hence, wavelength of \[0.25\text{ }\overset{\text{o}}{\mathop{\text{A}}}\,\]must be absent in the X-rays given out by the tube. Hence, the correction option is [c].You need to login to perform this action.
