Question: For a convex lens, if the object is at infinity, the image will be formed at: (2020)

Options:

Correct Answer: At the focus

Exam Year: 2020

Solution:

When the object is at infinity, the rays converge at the focus of the convex lens.

For a convex lens, if the object is at infinity, the image will be formed at: (2020)

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.

Lens Formula – Understanding how a convex lens focuses light and the relationship between object distance, image distance, and focal length.
Image Formation – Knowledge of how the position of the object affects the position of the image formed by a lens.
