Diameter of the objective lens of a telescope is \(250 \mathrm{~cm}\). For light of wavelength \(600 \mathrm{~nm}\), coming from a distant object, the limit of resolution of the telescope is close to
- A \(1.5 \times 10^{-7} \mathrm{rad}\)
- B \(2.0 \times 10^{-7} \mathrm{rad}\)
- C \(3.0 \times 10^{-7} \mathrm{rad}\)
- D \(4.5 \times 10^{-7} \mathrm{rad}\)
Answer & Solution
Correct Answer
(C) \(3.0 \times 10^{-7} \mathrm{rad}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { Limit of resolution }=\frac{1.22 \lambda}{d} \\ & =\frac{1.22 \times 600 \times 10^{-9}}{250 \times 10^{-2}}=3 \times 10^{-7} \mathrm{rad}\end{aligned}\)
