Convergence Insufficiency. Other names. Convergence disorder. Specialty. Ophthalmology, optometry. Convergence insufficiency is a sensory and neuromuscular anomaly of the binocular vision system, characterized by a reduced ability of the eyes to turn towards each other, or sustain convergence .
where is the amount of prism correction in prism dioptres, and is the angle of deviation of the light. For a prism with apex angle a {\displaystyle a} and refractive index n {\displaystyle n} , d = ( n − 1 ) a {\displaystyle d=(n-1)\,a} .
A burning apparatus consisting of two biconvex lens. A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.
A cube or rectangular prism is the most intuitive and common choice, but can be computationally expensive due to unnecessary amounts of solvent molecules in the corners, distant from the central macromolecules.
Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria .
Atomic Absorption Spectroscopy (AAS) measures the concentration of specific elements in a sample by analyzing their unique "fingerprint" in the form of an atomic absorption spectrum. Here's how it works: Step 1: Sample Preparation:**. The sample is typically dissolved in a suitable solvent (acids, water) to create a liquid solution.
Description. Well developed crystals of epidote, Ca 2 Al 2 (Fe 3+ ;Al) (SiO 4 ) (Si 2 O 7 )O (OH), crystallizing in the monoclinic system, are of frequent occurrence: they are commonly prismatic in habit, the direction of elongation being perpendicular to the single plane of symmetry. The name Epidote is derived from the Greek word 'epidosis ...
General definition In chromatography, the retardation factor, R , is the fraction of the sample in the mobile phase at equilibrium, defined as: [1] R = quantity of substance in the mobile phase total quantity of substance in the system {\displaystyle \ R={\frac {\mbox{quantity of substance in the mobile phase}}{\mbox{total quantity of substance ...
The Bohr–Sommerfeld model (also known as the Sommerfeld model or Bohr–Sommerfeld theory) was an extension of the Bohr model to allow elliptical orbits of electrons around an atomic nucleus. Bohr–Sommerfeld theory is named after Danish physicist Niels Bohr and German physicist Arnold Sommerfeld. Sommerfeld argued that if electronic orbits ...
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities.
