Q: For a convex lens, if the object is at infinity, the image will be formed at: (2020)
Solution: When the object is at infinity, the rays converge at the focus of the convex lens.
Steps: 6
Step 1: Understand what a convex lens is. A convex lens is thicker in the middle and thinner at the edges, and 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: Remember how light rays behave when they come from a distant object. Light rays coming from an object at infinity are parallel to each other.
Step 4: Learn about the focus of the lens. The focus is a specific point where light rays converge after passing through the lens.
Step 5: When parallel light rays enter a convex lens, they are bent inward and converge at the focus of the lens.
Step 6: Conclude that if the object is at infinity, the image will be formed at the focus of the convex lens.
