A) \[\text{3}.0\times \text{1}{{0}^{3}}\text{ Hz}\]
B) \[6.0\times \text{l}{{0}^{\text{3}}}\text{Hz}\]
C) \[\text{7}.\text{5 }\times \text{ 1}{{0}^{\text{5}}}\text{ Hz}\]
D) \[\text{1}.\text{5 }\times \text{ 1}{{0}^{\text{13}}}\text{ Hz}\]
Correct Answer: D
Solution :
\[p=\frac{hv}{c}\] \[\Rightarrow \] \[v=\frac{cp}{h}=\frac{(3\times {{10}^{8}})\times (3\cdot 3\times {{10}^{-29}})}{6\cdot 6\times {{10}^{-34}}}\] \[\mathbf{=1}\mathbf{.5\times 1}{{\mathbf{0}}^{\mathbf{13}}}\mathbf{Hz}\].
