Key Concepts

Converging Lenses

Converging lenses, also known as convex lenses, are thicker in the middle than at the edges. They function by bending parallel incoming light rays so that they meet at a specific point called the focal point. This property allows them to form real images when the object is placed beyond the focal point, and they are essential in various optical instruments such as cameras, microscopes, and corrective eyewear for farsightedness.

Diverging Lenses

Diverging lenses, commonly referred to as concave lenses, are thinner in the center and thicker at the edges. These lenses cause parallel incoming light rays to spread out as if they were emanating from a single point, known as the virtual focal point. They form virtual, upright, and reduced images, and are widely used in applications like eyeglasses for nearsightedness, peepholes, and certain types of optical devices where image correction or dispersion is needed.
