A convex lens bends inward. Hope this helps:)
convex
A prism has 3 flat faces while a convex lens has two curved faces. However the edge of a convex lense has a similar geometry to two adjacent faces of a prism.
a prism or convex lens
The periscope has several parts: the ocular lenses, the mirror or prism, inversion/reversion prisms, relay lenses, another mirror or prism, and objective lenses.
No
when it reflects off a surface like a mirror or a prism(the prism reflects, absorbs, and retracts light)
I would have to say the prism
No ! The images formed by a mirror are not perfect !!The finest images are those formed by a right angled PRISM . However the rays from the object need to fall perpendicularly on prism's surface . Thus for convenience mirrors are used .

Three if mirror images are considered different and two otherwise.
There are 2606 distinct convex nonahedrons with varying numbers of vertices, such as Johnson solid #14 (a triangular prism sandwiched between two pyramids) which has 8, and the heptagonal prism with 14. Concave solids could have even more!
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. One of these 257 shapes is a prismoid, and a prism is a special case of a prismoid in which the two hexagonal faces are congruent and parallel.
