For a thin prism, the deviation of violet light, is and that of red light, is (). The difference in the deviation between red and violet light, ( δ v − δ r ) = ( n v − n r ) A {\displaystyle (\delta _{v}-\delta _{r})=(n_{v}-n_{r})A} is called the Angular Dispersion produced by the prism.
An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...
A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, or the volume of water leaving an estuary at ebb tide. The inter-tidal prism volume can be expressed by the relationship: P=H A, where H is the average tidal range and A is the average surface area of the basin.
A parallelepiped is a prism with a parallelogram as base. Hence the volume V {\displaystyle V} of a parallelepiped is the product of the base area B {\displaystyle B} and the height h {\displaystyle h} (see diagram).
In the case of a triangular prism, its base is a triangle, so its volume can be calculated by multiplying the area of a triangle and the length of the prism: where b is the length of one side of the triangle, h is the length of an altitude drawn to that side, and l is the distance between the triangular faces.

Estimation using a wedge prism. A wedge prism can be used to quickly estimate basal area per hectare. To find basal area using this method, simply multiply your BAF (Basal Area Factor) by the number of "in" trees in your variable radius plot.
The area of a right heptagonal prism with height and with a side length of and apothem is given by: A = 7 L ⋅ ( a p + h ) {\displaystyle A=7L\cdot (a_{p}+h)} Volume [ edit ]
Multiple prism beam expander using r prisms ( M B 0 1 M ) {\displaystyle {\begin{pmatrix}M&B\\0&{\frac {1}{M}}\end{pmatrix}}} M is the total beam magnification given by M = k 1 k 2 k 3 ⋯ k r {\displaystyle M=k_{1}k_{2}k_{3}\cdots k_{r}} , where k is defined in the previous entry and B is the total optical propagation distance [ clarification ...
It deviates in the ultraviolet and infrared regions. In optics, Cauchy's transmission equation is an empirical relationship between the refractive index and wavelength of light for a particular transparent material. It is named for the mathematician Augustin-Louis Cauchy, who originally defined it in 1830 in his article "The refraction and ...
General triangular prism: b = the base side of the prism's triangular base, h = the height of the prism's triangular base L = the length of the prism see above
