Both reflecting and refracting telescopes suffer from :

Answer 1

Diffraction effects

Both reflecting and refracting telescopes suffer from diffraction effects.

Telescopes are monocular optical instruments, usually used in astronomy and are designed for the observation of remote objects. Telescopes have magnification for observing distant objects and use an arrangement of curved mirrors, lenses, or different devices. The two main kinds of telescopes are reflectors and refractors telescopes. The two telescopes suffer from diffraction effects such as the appearance of a rainbow of colours around the image.
