Hint: The image is brighter than refracting type telescope. Mirror requires one side of grinding and polishing. It has High resolution by using a mirror of large aperture. Due to a large aperture of mirrors, Reflecting telescopes will have high resolving power. The image is free from spherical and chromatic aberration, due to availability of paraboloidal mirrors.
Complete answer:
Reflecting telescopes use the single or a combination of curved mirrors creating the image by reflecting the light. Isaac Newton invented the reflecting telescope. Instead of lenses Reflecting telescopes use mirrors to focus the light . A concave mirror is used to collect light and reflects it back to a focal point. To gather the light out of the telescope, another mirror is used to the eyepiece to direct the light. a close up view of the object and upright image is obtained by the reflecting telescope . The different kinds of telescopes are Newtonian, Cassegrain, and Schmidt-Cassegrain telescopes. When light hits a mirror at any angle, it is reflected at the same angle as the principle of reflection. The parts of a reflecting telescope are eyepiece, optical tube, finderscope, focuser, aperture and mount.
Note: Hassle of operating in space is the main disadvantage in reflecting a telescope. Because it is larger in size it is more expensive. It is harder to repair it. The colours cannot focus at one point.
Not only to examine the visible region of the electromagnetic spectrum. Both the shorter- and longer-wavelength regions adjacent to the reflecting telescope. Reflecting telescopes are useful for astronomers to far objects more clearly. Reflecting telescopes is bigger and more powerful than refracting telescopes.
