Question
A concave lens is used to form an image of a real object.
The maximum distance of the image from the optical centre is:
- 4
- f²
- f
- ∞
Solution
The question seems to be incomplete or incorrectly formatted. However, I can provide a general answer about the image formed by a concave lens.
A concave lens, also known as a diverging lens, always forms a virtual, erect, and diminished image of the real object. The image is formed on the same side as the object and is always located between the optical center of the lens and its principal focus.
The distance of the image from the optical center of the lens depends on the object's distance from the lens. If the object is at infinity, the image is formed at the focus. As the object moves closer to the lens, the image also moves towards the lens and gets smaller. The image distance from the optical center can never be greater than the focal length of the lens.
Please provide a complete and correctly formatted question for a more specific answer.
