A MAGNIFYING glass is used to see smaller images or object bigger. Do you know how it works?
Let’s understand the physics of magnifying glass. A magnifying glass is a convex lens. Convex means curved outward, like the underside of a spoon. It is the opposite of concave or curved inward.[ihc-hide-content ihc_mb_type=”show” ihc_mb_who=”2,3″ ihc_mb_template=”1″ ]
A lens is something that allows light rays to pass through it and bends, or refracts, them as they do so. A magnifying glass uses a convex lens because these lenses cause light rays to converge or come together.
A magnifying glass, in effect, tricks your eyes into seeing what is not there. Light rays from the object enter the glass in parallel but are refracted by the lens so that they converge as they exit and create a “virtual image” on the retina of your eye.
This image appears to be larger than the object itself because of simple geometry: Your eyes trace the light rays back in straight lines to the virtual image, which is farther from your eyes than the object is and thus appears bigger.
