A plus lens has the effect of what on light rays?

• A. Diverging them
• B. Converging them
• C. Spreading them
• D. Reflecting them

Answer: (B)

A plus lens is a converging lens, meaning it has a specific shape, typically thicker in the center and thinner at the edges, that causes incoming parallel light rays to bend towards the center. When light rays enter a plus lens, they are refracted in such a way that they converge or meet at a point known as the focal point. This property is important in various optical applications, such as in magnifying glasses and converging optical designs used in eyeglasses for hyperopia (farsightedness). Other options such as diverging, spreading, and reflecting do not accurately describe the action of a plus lens. Diverging lenses, for instance, cause light rays to spread away from a focal point, while a plus lens brings them together. Spreading implies a different behavior related to light that diverges, and reflecting is a property associated with mirrors, not lenses. Therefore, identifying the function of a plus lens as converging light rays highlights its role in focusing and magnifying images, essential for clarity in vision and various optical tools.
