What is the primary function of a refracting telescope?

The primary function of a refracting telescope is to magnify distant objects using lenses. This type of telescope utilizes convex lenses to bend and focus light from distant celestial objects, allowing the viewer to see them in greater detail. The lenses work together to create an image that is larger and clearer than what is visible to the naked eye. By adjusting the lenses and their arrangement, observers can achieve higher levels of magnification and clarity.

In the context of telescopes, the use of lenses specifically distinguishes refracting telescopes from reflecting telescopes, which rely on mirrors to gather and focus light. While capturing images and studying heat emissions are potential outcomes or applications of using telescopes, the fundamental operation of a refracting telescope centers around the magnifying power of lenses.
