how are reflecting telescopes similar to devices that produce laser light?\no both use crystals to produce a beam of light.\no both have convex lenses that magnify objects.\no both have concave lenses that magnify objects.\no both use mirrors to reflect a beam of light.

Answer

Brief Explanations:

Reflecting telescopes use mirrors to reflect light to form an image. Laser - producing devices also use mirrors (resonator mirrors) to reflect light back and forth to amplify the light and produce a coherent laser beam. The other options are incorrect as reflecting telescopes don't use crystals to produce light, and they don't rely on convex or concave lenses for reflection (they use mirrors), and lasers don't use convex or concave lenses for their basic light - producing mechanism.

Answer:

D. Both use mirrors to reflect a beam of light.
