Why do magnifying glasses enlarge objects?
Show answer & explanation
Answer: Convex lens bends light inward
Magnification is an illusion — Wrong. Magnification is real optical refraction. Convex lenses bend light inward, creating genuinely enlarged virtual images your eye perceives.
Convex lens bends light inward ✓ — Correct! Magnifying glasses use convex lenses (thicker in center). When you hold them close to an object, light rays from the object refract (bend) inward through the lens. Your eye traces these bent rays backward, seeing a virtual image that's larger than the actual object. The focal length determines magnification power!
Curved surface adds detail — Wrong. Lenses don't add detail. They bend light to make objects appear larger. Convex lenses refract light inward, creating enlarged virtual images.
