→ A converging lens is thicker at its center than at its edges.

→ Also known as convex lenses, they cause parallel light rays passing through them to converge or focus at a point on the opposite side of the lens.

→ Converging lenses are capable of forming both real and virtual images depending on the placement of the object relative to the lens.

→ Real images formed by converging lenses are inverted and can be projected onto a screen. Virtual images are upright and cannot be projected.

→ Examples of converging lenses include magnifying glasses, camera lenses, and the lenses in binoculars and telescopes.

→ A diverging lens is thinner at its center than at its edges.

→ Also known as concave lenses, they cause parallel light rays passing through them to diverge or spread out.

→ Diverging lenses always form virtual images that are upright and reduced in size compared to the object.

→ The image formed by a diverging lens is always on the same side of the lens as the object, and it cannot be projected onto a screen.

→ Examples of diverging lenses include the lenses in eyeglasses used to correct nearsightedness (myopia) and the peephole lenses in doors.
