What does a refracting telescope use to collect and focus light?

1. Optical telescopes gather visible light from distant objects. 2. A refracting telescope does this with a large converging lens. 3. The lens bends the light inwards to a focus, where a second lens magnifies it. 4. A telescope built around a curved mirror is a reflecting telescope instead. _Source: Siyavula Natural Sciences Grade 8 (CC BY 4.0), 1. Refracting telescopes_
