Which telescope uses mirrors and lenses to magnify images of objects in the sky

The telescope that uses mirrors and lenses to magnify images of objects in the sky is called a reflecting telescope.

The telescope that uses mirrors and lenses to magnify object in the sky is OPTICAL TELESCOPE

Actually, the term "optical telescope" is a broad category that encompasses both reflecting and refracting telescopes. Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses to accomplish this. So, the statement that reflects the use of mirrors and lenses to magnify images of objects in the sky would be accurate for both types of telescopes.
