Position, Relative Size, and Nature of the Image Formed by a Concave Lens for an Object Placed at Infinity
When an object is placed at infinity, the rays of light coming from the object are parallel and almost parallel. In this scenario, let's discuss the position, relative size, and nature of the image formed by a concave lens.
Position of the Image
- The position of the image formed by a concave lens for an object placed at infinity is at the focus of the lens.
- This is because the rays of light coming from the object, after passing through the lens, appear to diverge from the focus of the lens.
Relative Size of the Image
- The image formed by a concave lens for an object placed at infinity is diminished in size.
- This means that the image is smaller than the actual object.
Nature of the Image
- The image formed by a concave lens for an object placed at infinity is virtual.
- A virtual image is formed when the rays of light do not actually converge at the image position but appear to diverge from it when traced backward.
Explanation
- When parallel rays of light pass through a concave lens, they diverge as if they are coming from the focus of the lens.
- In the case of an object placed at infinity, the rays of light are almost parallel.
- As these parallel rays of light pass through the concave lens, they appear to diverge from the focus.
- The brain perceives the apparent intersection point of these diverging rays of light as the image.
- Since the rays of light do not actually converge at the image position, the image formed is virtual.
- Furthermore, the image appears smaller than the actual object, thus diminished in size.
Therefore, the correct answer is option A: At focus, diminished, and virtual.
