Text Solution

AI Generated Solution

To understand why the aperture and focal length of the objective of a telescope are large, we can break down the explanation into two parts: the significance of the aperture and the importance of the focal length. ### Step-by-Step Solution: 1. **Understanding Aperture**: - The aperture of a telescope refers to the diameter of the objective lens or mirror. A larger aperture allows more light to enter the telescope. - **Reason**: More light entering the telescope increases the intensity of the image formed. This is crucial for observing faint celestial objects, as it enhances the brightness and clarity of the images. ...
