Explanation:

The largest telescope in the world has a reflector with an aperture of 200 inches. The choice of aperture size is based on the desired optical performance of the telescope. In this case, the aperture size is chosen to achieve high accommodation power.

Accommodation Power:

Accommodation power is the ability of the eye to adjust its focus to see objects at different distances. In the case of a telescope, accommodation power refers to the ability of the telescope to focus on objects at different distances. A telescope with high accommodation power can focus on objects at different distances, making it useful for observing objects in space that are at varying distances from Earth.

Aperture Size and Accommodation Power:

The aperture size of a telescope plays a crucial role in determining its accommodation power. A larger aperture size allows more light to enter the telescope, resulting in a brighter and clearer image. This, in turn, improves the accommodation power of the telescope.

Conclusion:

Therefore, the choice of an aperture size of 200 inches for the largest telescope in the world is based on the desired optical performance of the telescope, specifically its accommodation power. The larger aperture size improves the accommodation power of the telescope, making it useful for observing objects in space that are at varying distances from Earth.
