A) 0.5m
B) 5m
C) 6mm
D) 7cm
Correct Answer: C
Solution :
If \[x\] is the distance between two objects and d is the distance between the telescope and the two objects, then\[d\theta =\frac{x}{d}=\frac{1.22\lambda }{D}\] or \[x=\frac{1.22\lambda d}{D}=\frac{1.22\times 5000\times {{10}^{-10}}\times 1000}{0.10}m\] \[=6.0\times {{10}^{-3}}\,\approx \,\,\text{6}\,\,\text{mm}\]You need to login to perform this action.
