An object is kept between infinity and 2F1 of a convex lens. Explain the location of image with the help of a suitable ray diagram.
Answers
Image is diminished, real and inverted.
Explanation:
A convex lens or converging lens in one in which parallel rays of light pass through to get refracted and converge at the principal focus.
When the object is placed at 2F, the image will be of the same size. The image formed is real and inverted in nature.
However, if we move the object further beyond 2F, a diminished, real and inverted image is formed between principal focus, F2 and centre of curvature, C2 at the opposite side when an object is placed beyond C1 of a convex lens. Image is diminished, real and inverted.
Please refer to picture 1 for the diagram.
Convex lens converge parallel rays coming from object at infinity and a highly diminished (point sized), real and inverted image is formed at principal focus F2. Image is highly diminished, real and inverted.
Please refer to picture 2 for the diagram.
