In a prism, the angle of deviation (δ) decreases with increase in the angle of incidence (i) up to a particular angle.This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation (denoted by δ min, D λ, or D m).
Illustration of the relationship between optical power in dioptres and focal length in metres. A dioptre (British spelling) or diopter (American spelling), symbol dpt, is a unit of measurement with dimension of reciprocal length, equivalent to one reciprocal metre, 1 dpt = 1 m −1.
Religious syncretism is the blending of religious belief systems into a new system, or the incorporation of other beliefs into an existing religious tradition.. This can occur for many reasons, where religious traditions exist in proximity to each other, or when a culture is conquered and the conquerors bring their religious beliefs with them, but do not succeed in eradicating older beliefs ...
A Pellin–Broca prism is a type of constant-deviation dispersive prism similar to an Abbe prism. The prism is named for its inventors, the French instrument maker Ph.
Phenobarbital is occasionally prescribed in low doses to aid in the conjugation of bilirubin in people with Crigler–Najjar syndrome, type II, [31] or in people with Gilbert's syndrome. [32] In infants suspected of neonatal biliary atresia , phenobarbital is used in preparation for a 99m Tc-IDA hepatobiliary ( HIDA ; h epatobiliary 99m Tc- i ...
In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used in constructing another polyhedron.
Galantamine is a type of acetylcholinesterase inhibitor.It is an alkaloid extracted from the bulbs and flowers of Galanthus nivalis (common snowdrop), Galanthus caucasicus (Caucasian snowdrop), Galanthus woronowii (Voronov's snowdrop), and other members of the family Amaryllidaceae, such as Narcissus (), Leucojum aestivum (snowflake), and Lycoris including Lycoris radiata (red spider lily).
