A) \[0.001\,\,rad\]
B) \[0.01\,\,rad\]
C) \[1\,\,rad\]
D) \[0.1\,\,rad\]
Correct Answer: A
Solution :
Using the formula \[d\sin \theta =n\,\,\lambda \] For\[n=1\]we have\[\sin \theta =\frac{\lambda }{d}\] \[\sin \theta =\frac{550\times {{10}^{-9}}}{0.55\times {{10}^{-3}}}={{10}^{-3}}\,\,rad\] \[=0.001\,\,rad\]You need to login to perform this action.
