पर्याय

• Refracting telescope

• Galilean telescope

• Cassegrain telescope

• Reflecting telescope

Answer 1

A refracting telescope uses two convex lenses; a large objective and a small eyepiece. In contrast, a reflecting telescope uses a concave mirror to reflect light internally, and a Galilean telescope uses a diverging lens as the eyepiece.
