A prism is named for the shape of its bases . For example, if the base is a pentagon, then it is called a “pentagonal prism.” A pyramid is a type of polyhedron that has one special face called the base. All of the other faces are triangles that all meet at a single vertex.
How do you name a prism or a pyramid?

How does a prism work?
A prism is a piece of glass or plastic in the shape of a triangle. ... A prism works because the different colors of light travel at different speeds inside the glass . Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up.

angle of prism is the angle between the two surface of the prism from which the light enters into the prism and from the light goes out after refraction .
What are the properties of a prism?
A prism is a type of three-dimensional (3D) shape with flat sides. It has two ends that are the same shape and size (and look like a 2D shape). It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.
