A) 0.5 m
B) 5 m
C) 5 mm
D) 5 cm
Correct Answer: C
Solution :
\[\theta =\frac{x}{d}=\frac{1.22\,\lambda }{a}\] \[\Rightarrow x=\frac{1.22\times d}{a}\] \[=\frac{1.22\times 5000\times {{10}^{-10}}\times {{10}^{3}}}{10\times {{10}^{-2}}}\]= 6.1 mm i.e. order will be 5 mm.You need to login to perform this action.
