The image formed by an astronomical telescope is

Correct option is B

The correct answer is (B) virtual and magnified

Explanation:

In an astronomical telescope, the image formed by the telescope's eyepiece lens is virtual and magnified. Here's how it works:

1. The objective lens of the telescope forms a real, diminished image of a distant object (like a planet or star).

2. The eyepiece lens then magnifies this real image, creating a virtual image for the observer to view. The virtual image appears magnified through the eyepiece, making it easier to observe distant celestial objects.

In this case, the observer is looking at the virtual image formed by the eyepiece, which is magnified compared to the object in the sky.

Information Booster:

• Objective lens: Forms a real and diminished image.

• Eyepiece lens: Acts like a magnifier to increase the size of the image, making it appear virtual and magnified for the observer.

• Astronomical telescopes are designed to provide a clearer, magnified view of distant objects in space, making the virtual image appear larger.

Additional Information:

• Virtual and diminished: This type of image is typically not formed by astronomical telescopes.

• Real and magnified: This is typical of a camera, where the image is captured on a screen or film.

• Real and diminished: Formed in some optical devices, but not in telescopes where magnification is needed for observation.
