Option A: Chromatic aberrationis a problem with reflecting telescopes. Large glass lenses with flawless interiors are challenging to produce. There are various surfaces to shape and polish on refractivetelescopes.Compared to huge mirrors, large glass lenses are more challenging to support.Telescopesare instruments used to observe and study celestial objects such as stars, planets, galaxies, and nebulae. They work by collecting and focusing electromagnetic radiation from these objects, allowing astronomers to study their properties and characteristics. Telescopes come in a variety of designs, such asrefracting, reflecting, andcatadioptric telescopes. Refracting telescopes use lenses to bend and focus light while reflecting telescopes use mirrors to do the same. Catadioptric telescopes use both lenses and mirrors to focus light. Modern telescopes can also operate in a variety of wavelengths, including visible light,radio waves, and X-rays. In recent years, the development of space telescopes has enabled astronomers to observe the universe beyond the limitations of the Earth's atmosphere. Telescopes have played a crucial role in advancing our understanding of the universe and continue to be an essential tool in modern astronomy.Learn more abouttelescopeshere:brainly.com/question/24151887#SPJ4...
