If an object is placed at between F and 2F in front of a Convex Lens,...
When an object is placed between the focal point (F) and twice the focal length (2F) in front of a convex lens, the image formed will be beyond 2F. This can be explained using the concepts of ray diagrams and the characteristics of convex lenses.
Ray Diagram:
A ray diagram can be used to determine the position and characteristics of the image formed by a convex lens. In this case, we will draw three rays: one parallel to the principal axis, one passing through the center of the lens, and one passing through the focal point.
Characteristics of Convex Lenses:
1. Parallel rays of light converge after passing through a convex lens.
2. Rays passing through the center of the lens continue in a straight line without any deviation.
3. Rays passing through the focal point on one side of the lens emerge parallel to the principal axis on the other side.
Explanation:
1. Draw a horizontal line representing the principal axis of the lens.
2. Mark the focal point (F) on the principal axis, which is half the distance of the lens's focal length.
3. Place the object between F and 2F on the principal axis.
4. Draw a ray from the top of the object parallel to the principal axis. This ray will pass through the lens and converge at a point on the other side of the lens.
5. Draw a ray from the top of the object through the center of the lens. This ray will continue in a straight line without any deviation.
6. Draw a ray from the top of the object towards the focal point on the same side of the lens. This ray will emerge parallel to the principal axis on the other side of the lens.
7. The point where the rays intersect after passing through the lens is the position of the image.
8. In this case, the converging ray and the parallel ray intersect beyond 2F, indicating that the image is formed beyond 2F.
Therefore, the correct answer is option 'A' - the image formed will be beyond 2F.

The image formed will be beyond 2F, enlarged, real and inverted.
