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

Solution: A concave lens always forms a virtual and upright image regardless of the object's position.

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 placed 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 light rays from an object at infinity pass through a concave lens, they spread out or diverge.
Step 5: The diverged rays appear to come from a point behind the lens. This point is where the virtual image is formed.
Step 6: A virtual image cannot be projected on a screen because it is formed by rays that do not actually converge.
Step 7: The virtual image formed by a concave lens is always upright (not inverted) and smaller than the object.
