In an astronomical telescope, the lens called eyepiece forms an image of a distant object that is:
Correct answer: D. Virtual and magnified
- A. Real and diminished
- B. Real and magnified
- C. Virtual and diminished
- D. Virtual and magnified
Explanation
An astronomical telescope is an optical instrument which is used to see the magnified image of distant heavenly bodies. The final image formed by an astronomical telescope is always virtual, inverted and magnified.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
