A) \[1.2\times {{10}^{17}}Hz\]
B) \[1.2\times {{10}^{19}}Hz\]
C) \[6\times {{10}^{15}}Hz\]
D) \[2.4\times {{10}^{18}}Hz\]
Correct Answer: B
Solution :
Maximum frequency of emitted radiation \[{{v}_{\max }}=\frac{eV}{h}\] \[=\frac{1.6\times {{10}^{-19}}\times 50\times {{10}^{3}}}{6.6\times {{10}^{-34}}}\] \[=1.2\times {{10}^{19}}Hz\]
