Question

which is one advantage of using a reflecting telescope instead of a refracting telescope? reflecting telescopes are less expensive. reflecting telescopes produce clearer images. reflecting telescopes require only concave lenses. reflecting telescopes usually take up less space.

Explanation:

Refracting telescopes suffer from chromatic aberration which distorts images. Reflecting telescopes use mirrors instead of lenses and avoid this issue, producing clearer images. They are not necessarily less expensive, require mirrors not just concave lenses, and can be large in size.

Answer:

Reflecting telescopes produce clearer images.
