A) \[16.25\times {{10}^{20}}Hz\]
B) \[9.20\times {{10}^{19}}Hz\]
C) \[7.15\times {{10}^{15}}Hz\]
D) \[5.09\times {{10}^{14}}Hz\]
Correct Answer: D
Solution :
We know that frequency (v) \[=\frac{velocity\text{ (}c)}{wavelength\text{ (}\lambda )}\] where c is speed of light. \[\therefore \] \[v=\frac{3\times {{10}^{8}}}{5893\times {{10}^{-10}}}-5.09\times {{10}^{14}}Hz\]
