Explanation:

a) A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope).

b) A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. ... The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics.

c) There are two types of magnification lenses Simple and Compound lenses. Simple Lenses: It refers to a simple lens that we use to magnify an object. Also, a single lens is the lens that we use to read the newspaper, magnify the things or objects in the front.
