Question

How would a pencil look like if you saw it through a convex lens? (Assume the pencil is close to the lens). Is the image real or virtual?

Answer 1

When a pencil is seen through a convex lens placed close to it, the image appears larger (magnified) than its actual size and upright. The reason for this is that the pencil is placed within the focus of the lens, and therefore, the image formed is virtual.
