What are the differences between prisms and cylinders?
Prisms have two parallel and congruent bases connected by rectangular lateral faces, while cylinders have two circular bases connected by a curved lateral surface. Prisms have flat sides and edges, while cylinders have a curved surface.
What happens to the ray of light when it goes straight into the prism along the normal?
A ray of light, no matter what its wavelength is, entering one face of the prism along the normal, continues along the same direction straight into the glass, just as it does when it enters a window-pane or any other medium along the normal. Since the faces of the prism are not parallel, however, the ray of light does not approach the next face along the normal, and it refracts there as it traverses the glass/air interface. There, the angle of refraction depends slightly on the wavelength, so the colors spread somewhat as they cross that boundary. If the faces of the window-pane were not parallel, then most of the things you see through the window would have pretty colored bands around it. It would be a total nuisance.
Does a prism have an apex?
No, a prism does not have an apex. A prism is a solid geometric figure with two parallel and congruent bases that are connected by lateral faces. The apex refers to the highest point or vertex of a shape, which is not applicable to prisms.
Why there is no dispersion of light refracted through a rectangular glass slab?
A prism breaks up white light into the light spectrum that shows each different color. However, a rectangle does not have the edges needed to break the light up.
What is the rule for prisms?
A prism is a three-dimensional shape with two parallel and congruent bases connected by rectangular faces. The volume of a prism is given by multiplying the area of the base by the height of the prism. The surface area of a prism is calculated by adding the areas of all its faces.
How would you describe the height of a cylinder or prism?
It is the linear distance between the two parallel and identical faces (which are also called the bases).It is the linear distance between the two parallel and identical faces (which are also called the bases).It is the linear distance between the two parallel and identical faces (which are also called the bases).It is the linear distance between the two parallel and identical faces (which are also called the bases).
Does a dodecahedron have parallel faces?
Yes! a Dodecahedron has parallel faces.
What shape has parallel hexagonal faces at each end with the faces between them equal?
Don't know find it yourself
What are parallel faces in 3D shapes?
They are faces such that the perpendicular distance between them is the same wherever on either face you measure it.
What solid figure has three pairs of parallel parallel faces and all faces are congruent?
A cube has three pairs of parallel faces and all faces are congruent.
How many parallel faces does a dodecahedron have?
A dodecahedron has 0 parallel faces
Does a octahedron have any parallel faces or edges?
its has parallel faces and edges
How many parallel faces does an octahedron have?
There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
Does a pyramid always have parallel faces?
A pyramid never has parallel faces. Any two faces intersect.
What has 3 parallel faces?
A cube has six faces, which are arranged in three sets of two parallel faces.
Does a tetrahedron have parrallel faces?
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
Does a octagonal prism have parallel faces?
Usually, a pair of parallel bases and four pairs of parallel lateral faces.
