Q: What happens to the image formed by a concave lens when the object is placed at infinity?

Solution: When an object is placed at infinity, a concave lens forms a virtual image at its focal point, which is upright.

Steps: 7

Step 1: Understand what a concave lens is. A concave lens is thinner in the middle and thicker at the edges.
Step 2: Know that when we say an object is at infinity, it means the object is very far away from the lens.
Step 3: Remember that a concave lens always diverges light rays that pass through it.
Step 4: When parallel light rays from an object at infinity hit the concave lens, they bend outward.
Step 5: The diverging rays appear to come from a point on the same side of the lens as the object. This point is called the focal point.
Step 6: The image formed by the concave lens is virtual, meaning it cannot be projected on a screen.
Step 7: The virtual image is located at the focal point of the lens and is upright (not inverted).
