Nearly all large optical telescopes built today arereflecting telescopes.Reflecting telescopes use mirrors to gather and focus light, providing advantages over refracting telescopes that use lenses. Reflecting telescopes are better suited for large-aperture designs due to the difficulties inmanufacturingand supporting large lenses. The primary mirror of a reflecting telescope collects and reflects light onto a secondary mirror, which then directs the light to the eyepiece or detector. Reflecting telescopes offer various advantages, such asreducedchromatic aberration, better light-gathering capability, and the ability to accommodate larger apertures. These factors make reflecting telescopes the preferred choice for most modern astronomical observations, allowing astronomers to study celestial objects with greater detail and sensitivity.Know more aboutreflecting telescopeshere:brainly.com/question/19349900#SPJ11...
