Resolving power of a telescope can be increased by increasing :
- A Wavelength of light incident at telescope
- B Diameter of eye piece
- C Focal length of eyepiece
- D Diameter of Objective lens
Answer & Solution
Correct Answer
(D) Diameter of Objective lens
Step-by-step Solution
Detailed explanation
The resolving power of a telescope is defined as \(\frac{D}{1.22 \lambda}\), where \(D\) is the diameter of the objective lens. Therefore, increasing the diameter allows the telescope to distinguish between much closer objects, effectively increasing its resolution. D) Diameter…
