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.

THE CORRECT ANSWER IS B "Reflecting telescopes produce clearer images."
I GOT IT RIGHT ON THE TEST

CONGRATSSS!

Explanation:

Here's why your answer is correct:

A reflecting telescope is one that makes use of mirrors. A mirror, unlike a lens, can be very thin. It is not necessary for a larger mirror to be thicker. By bouncing off the mirror, light is focused. So all the mirror needs is the correct curved shape. Making a large, near-perfect mirror is substantially easier than making a large, near-perfect lens. Mirrors are also easier to clean and polish than lenses because they are one-sided.

So option B is correct
