A) the increase m the resolving power by 2.54 times for the same \[\lambda \]
B) the increase in the limiting angle by 2.54 times for the same \[\lambda \]
C) decrease in the resolving power
D) no effect on the limiting angle
Correct Answer: A
Solution :
Resolving power of telescope \[=\frac{D}{1.22\,\lambda }\] where D = diameter of objective. So, on using the telescope of diameter 2.54 m in place of 1 m, resolving power will increase by 2.54 times for same \[\lambda \].
