A) \[{{10}^{-4}}m\]
B) \[{{10}^{-3}}mm\]
C) \[{{10}^{-4}}\times \pi m\]
D) \[\pi \times {{10}^{-3}}m\]
Correct Answer: A
Solution :
By using \[\beta =\frac{(a+b)\lambda }{2a(\mu -1)\alpha }=\frac{(0.3+0.7)\times 180\pi \times {{10}^{-9}}}{2\times 0.3(1.54-1)\times \left( 1\times \frac{\pi }{180} \right)}\]= \[{{10}^{-4}}m\]
