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

Solution: When the object is at infinity, the rays converge at the focal point, forming a real and inverted image.

Steps: 5

Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and thinner at the edges. It bends light rays that pass through it.
Step 2: Know what it means for an object to be at infinity. When we say the object is at infinity, it means it is very far away from the lens.
Step 3: Learn about light rays from a distant object. When light rays come from an object at infinity, they are almost parallel when they reach the lens.
Step 4: Observe how the lens behaves. A convex lens will bend these parallel rays towards the focal point, which is a specific point on the opposite side of the lens.
Step 5: Identify the characteristics of the image formed. The image formed at the focal point is real (it can be projected on a screen) and inverted (upside down compared to the object).
