Definition of the Index of Refraction The index of refraction is a numerical value that represents the ratio between the speed of light in a vacuum and the speed of light in a given material. It determines how much the direction of light changes as it passes through a medium, such as air...
Definition A light guide is a device used to direct light from a light source (commonly an LED) to a place where the light is needed. Light guides are also sometimes referred to as light pipes. Light guides are usually made of glass or plastic, which typically have an index of refracti...
What is height of collimation? What is the Karman line? What is a projectile? What is the distance between rarefactions called? What is a sea mile? What is the definition for elevation? What is the air like in the stratosphere?
Refraction & Dispersion: Definition, Snell's Law & Index of Refraction from Chapter 5/ Lesson 14 125K When a light wave passes from one medium into another, it changes direction in a process called refraction. This lesson investigates the properties of refraction, including the index of refracti...
Fresnel Equations Definition: Fresnel Equations describe the ratios of electric fields of reflected and transmitted waves to the incident wave. Light Reflection and Transmission: These equations explain how light reflects and transmits at the boundary between two different mediums. ...
What is the definition of isodynamic? adjective.pertaining to or characterized by equality of force, intensity, or the like. noting or pertaining to an imaginary line on the earth's surface connecting points of equal horizontal intensity of the earth's magnetic field. ...
The fundamental limit on propagation delay is the speed of light (c). Since nothing can travel faster than light and light has a finite speed, there will always be some delay as a signal moves from source to destination. This is true for all signals from small to great and distances from...
Medical Definition of convexo-concave 1 : concavo-convex. 2 :having the convex side of greater curvature than the concave. What is the use of convexo-concave lens? Concave Lenses Are for the Nearsighted, Convex for the Farsighted. Concave lenses are used ineyeglasses that correct nearsighted...
Radio propagation definitionRadio propagation is the way radio waves travel or propagate when they are transmitted from one point to another and affected by the medium in which they travel and in particular the way they propagate around the Earth in various parts of the atmosphere....
In optics, a material with a high dielectric constant will have a high refractive index, which means it can bend light more than a material with a low dielectric constant. Additionally, the dielectric constant is used in many sensing applications, such as in capacitive sensors, dielectric spectro...
