A small object is placed at the focus on the left side of a convex lens. Where will the image be formed?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. At infinity on the right side of the lens.
When a small object is placed at the focus on the left side of a convex lens, the image will be formed at infinity on the right side of the lens. This occurs because rays of light passing through the focus on one side of the lens emerge parallel to each other on the other side, resulting in an image at infinity.
