How does light behave when passing through a converging lens?

• A. It spreads out equally in all directions
• B. It bends inward and converges at a focal point
• C. It is reflected back in the same direction
• D. It passes straight through without bending

Answer: (B)

When light passes through a converging lens, it bends inward due to the refractive properties of the lens material. A converging lens is thicker in the center than at the edges, and its shape causes incoming parallel rays of light to refract, or bend, toward the optical axis as they pass through. This bending effect results in the rays converging or coming together at a specific point known as the focal point. The ability of the converging lens to focus light makes it essential in various optical devices, such as cameras and magnifying glasses. Understanding this behavior is crucial for applications in optics, where precise manipulation of light is required.
