The magnifying power of a telescope can be increased by:
Correct answer: D. Fitting an eyepiece of high power.
- A. Increasing the focal length of the eyepiece.
- B. Increasing the distance of the object.
- C. Fitting an eyepiece of low power.
- D. Fitting an eyepiece of high power.
Explanation
D is the right option because The magnifying power of a telescope is directly related to the power of the eyepiece. Fitting an eyepiece of high power increases the magnifying power of the telescope, allowing for greater magnification of distant objects.

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.
