​A concave lens spreads light rays, forming a smaller, upright image.

​A convex lens focuses light rays to a point.

• When the object is far from the lens, the image formed is smaller and inverted.

• When the object is close to the convex lens, the image is larger than the object and is upright .

A convex mirror spreads light rays and produces only upright, smaller images.

​​A concave mirror focuses light rays to a point and produces an upright, magnified image if the mirror is close to the object (e.g., make-up mirrors).

• If the concave mirror is far from the object, the image is inverted (upside down) and smaller than the object.
