How are reflecting telescopes similar to devices that produce laser light?

a.)both use crystals to produce a beam of light.
b.)both have convex lenses that magnify objects.
c.)both have concave lenses that magnify objects.
d.)both use mirrors to reflect a beam of light.

Reflecting telescopes have a little mirror on the tube and it gets the light from space and reflect it into the rest of the telescope. Lasers use that but on the opposite way, so D

Answer;

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

Explanation;A reflecting telescope is a type of telescope that uses one or more than one combination of curved mirrors to reflect light and hence form an image of an object. Reflecting telescope was development as an improvement of refracting telescope and has many advantages which include; production of clear images, and also they can gather light from objects farther in space. Devices that produce laser lights also use mirrors to reflect a beam of light.

2. they have negligible mass.
