A) 3 mm
B) 0.11 mm
C) 2 mm
D) 4 mm
Correct Answer: B
Solution :
\[a=0.3\operatorname{m},b=07\operatorname{m}.\,\]Angle of prism, \[A=1{}^\circ .\] |
\[\therefore \]\[D=a+b=0.3+0.7=1m.\] |
\[d=2a(\mu -1)A=2\times 0.3(1.5-1)\times \frac{\pi }{180}\] |
\[=0.0052\operatorname{m}\] |
Now \[\beta =\frac{D\lambda }{d}=\frac{1\times 6000\times {{10}^{-10}}}{0.0052}\] |
\[=1.15\times {{10}^{-4}}m=0.115\] |
