What is the main function of a telescope?

• A. To collect sound waves
• B. To magnify and collect light from distant objects
• C. To create thermal images
• D. To filter air samples

Answer: (B)

The primary function of a telescope is to magnify and collect light from distant objects, allowing observers to see them more clearly and in greater detail. Telescopes achieve this by using a combination of lenses or mirrors to gather and focus light. As a result, they can display celestial bodies, such as stars, planets, and galaxies, that are otherwise too faint or too far away to be observed with the naked eye. The design of telescopes, whether they are refractor types that use lenses or reflector types that use mirrors, is specifically aimed at enhancing the amount of light that can be captured, improving the visibility of distant phenomena. This fundamental capability enables astronomers to explore the universe, analyze the composition of celestial objects, and study their motion and behavior, making telescopes indispensable tools in the field of astronomy.
