Convex lens converges incident rays. Hence the rays to converge at a point in front of the lens. So image distance is positive here. We can easily clarify that the focal length is positive direction for a Convex lens while negative with concave lens. What is the sign of focalRead More →
Magnifying glasses make objects appear larger because their convex lenses (convex means curved outward) refract or bend light rays, so that they converge or come together. … When light bounces off an object and travels to your eyes, those light rays travel parallel to each other.
