Answer:

Concave mirror

Step-by-step explanation:

  • Reflecting telescopes is a type of telescope that uses mirrors instead of lens. This is because mirrors are lighter and thus are easier to make perfectly smooth as compared to lenses.
  • Reflecting telescopes use concave mirrors for the purposes of bringing light gathered to a certain focus.
  • Concave mirror in reflecting telescopes collects parallel rays from the object and forms an image at the focal point.
