Prismás
Prismás is a term that can refer to several concepts, primarily related to optics and geometry. In its most common usage, it refers to a prism, a transparent optical element with flat, polished surfaces that refract light. Prisms are typically triangular in cross-section. When light enters a prism, it undergoes refraction, bending at the interface between the two optical media. If the prism is made of glass and surrounded by air, light will bend towards the normal upon entering and away from the normal upon exiting. This bending of light causes a deviation in the path of the light ray.
The dispersion of light is a key phenomenon associated with prisms. Because the refractive index of the
In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is
