A) 0.1 mm
B) 1.0 mm
C) 0.5 mm
D) 0.2 mm
Correct Answer: A
Solution :
Position of nth minima \[{{x}_{n}}=\frac{n\lambda D}{d}\] \[\Rightarrow \] \[5\times {{10}^{-3}}=\frac{1\times 5000\times {{10}^{-10}}\times 1}{d}\] \[\Rightarrow \] \[d={{10}^{-4}}\,\,m=0.1\,\,mm\].You need to login to perform this action.
