Question

A reflecting telescope have more advantages than refracting telescope.

• A. True
• B. False

Answer 1

The correct option is A True

A reflecting telescope uses curved mirrors to form an image. Reflecting telescopes have the following advantages over refracting telescopes:
1. In order to get a bright image of a source, large mirrors are necessary, but it is easier to make large mirrors as compared to making large lenses.
2. Big mirrors can be made by combining several smaller pieces. The weight of a large mirror is less than that of a lens of the same size.
3. The images formed by mirrors do not have errors of colour.
