A) \[1.5\,\,mm\]
B) \[1.0\,\,mm\]
C) \[0.5\,\,mm\]
D) none of these
Correct Answer: C
Solution :
Using the relation \[B=\frac{\lambda \,\,D}{d}=\frac{550\times {{10}^{-9}}\times 1}{1.1\times {{10}^{-3}}}\] \[=500\times {{10}^{-6}}=0.5\,\,mm\] This is the separation between the consecutive bright frings. The separation between the consecutive bright and dark fringes will be\[\frac{\beta }{2}\].You need to login to perform this action.
