A) \[4.8\,\mu m\]
B) \[8.23\,\mu m\]
C) \[14.98\,\mu m\]
D) \[3.78\,\mu m\]
Correct Answer: A
Solution :
\[\Delta x=\frac{dy}{D}\,\,-\,\,(\mu -1)\,t=0\] \[y=(\mu -1)\,\,\frac{tD}{d}\] \[4\beta =(\mu -1)\frac{tD}{d}\,\,\Rightarrow \,\,4\lambda =(\mu -1)\,t\] \[t=\left( \frac{4\lambda }{\mu -1} \right)\,\,=\,\,\frac{4\times 6000\times {{10}^{-10}}}{1.5-1}\] \[t\,\,=\,\,4.8\,\,\times \,\,{{10}^{-6}}\] \[t\,\,=\,\,4.8\,\mu m\]You need to login to perform this action.
