A) \[4.84\times {{10}^{16}}\]
B) \[2.42\times {{10}^{16}}\]
C) \[3.84\times {{10}^{16}}\]
D) None of these
Correct Answer: A
Solution :
Here: \[E=200eV=200\times 1.6\times {{10}^{-19}}J\] \[=3.2\times {{10}^{-17}}J\] Using the relation \[E=hv\] So, frequency of photon, \[v=\frac{E}{h}=\frac{3.2\times {{10}^{-17}}}{6.6\times {{10}^{-34}}}=4.84\times {{10}^{16}}Hz\]
