A) \[16:25\]
B) \[9:1\]
C) \[4:5\]
D) \[5:4\]
Correct Answer: D
Solution :
Resolving power of an optical instrument is inversely proportional to\[\lambda \]i.e.,\[R.P.\propto \frac{1}{\lambda }\] \[\therefore \] \[\frac{Resolving\text{ }power\text{ }at{{\lambda }_{1}}}{Resolving\text{ }power\text{ }at{{\lambda }_{2}}}=\frac{{{\lambda }_{2}}}{{{\lambda }_{1}}}\] \[=\frac{5000}{4000}=5:4\]You need to login to perform this action.
