A) \[7.692\,\,rad\]
B) \[7.692\,\,\pi \,\,rad\]
C) \[\frac{7.692}{\pi }rad\]
D) \[\frac{7.692}{3\pi }rad\]
Correct Answer: B
Solution :
Phase difference\[\phi =\frac{2\pi }{\lambda }x\] \[=\frac{2\pi \times 2.1\times {{10}^{-6}}}{5460\times {{10}^{-10}}}\] \[=7.692\,\,\pi \,\,rad\]You need to login to perform this action.
