Following are the types of mirrors that are most widely used:

Plane mirror: The images formed from a plane mirror are the reflected images in their normal proportions but reversed from left to right. These are the most widely used mirrors.

Convex mirror: These are the spherical mirror that is curved outward and the image obtained is virtual, diminished and erect for a real object.

Concave mirrors: These are the spherical mirror that is curved inward and the image obtained from these mirrors depend on the placement of the object.

Lenses: A lens is a part of a reflecting material like glass or plastic but curved from both sides. Lenses are unlike mirrors that have a reflecting surface only on one side. Depending upon its shape a lens can be categorized as:

  • Convex Lens - A Convex Lens is curved outwards. It is thicker in the centre and narrows down at the edges. It merges the light rays passing through it at a certain point. Therefore, it is also called a Converging Lens.

  • Concave Lens - A Concave Lens is curved inwards. It has wider edges and a thinner centre. It reflects back the light that travels through it in different directions. Therefore, it is also called a Diverging Lens.

In terms of reproduction in plants

Yogita Ingle 4 days, 7 hours ago

Many invertebrates and a significantly smaller number of vertebrates are hermaphrodites. A hermaphrodite possesses both male and female reproductive organs during their life span. Some of these animals self-fertilize, while others require a partner. It is a condition which enables a form of sexual reproduction in which both partners can act as the "female" or "male". Examples: Snails,worms and about 21 families of fish are Hermaphrodites.
