Question

Write two advantages of a reflecting telescope over a refracting telescope

Answer 1

Reflecting telescopes have many advantages over refracting telescopes. Mirrors don't cause chromatic aberration and they are easier and cheaper to build large. The are also easier to mount because the back of the mirror can be used to attach to the mount. ... Some telescopes use a combination of mirrors and lenses.

Answer 2

Answer:

Advantages

* Spherical aberration

* Chromatic aberration

Explanation:

* Spherical aberration

Reason :

Spherical aberration is reduced in the case of reflecting telescopes by using a mirror objective in the form of a paraboloid.

* Chromatic aberration

Reason :

There is no chromatic aberration in the case of reflecting telescopes as the objective is a mirror.
