Laser
A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser light is usually spatially -
Photodiode
A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Photodiodes are similar to regular semiconductor diodes except that they may be either -
Interference
In physics, interference is the addition (superposition) of two or more waves that result in a new wave pattern. As most commonly used, the term interference usually refers to the interaction of waves which are -
Compton scattering
In physics, Compton scattering or the Compton effect is the decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, when it interacts with matter. Inverse Compton scattering also exists, where -
Phase (waves)
The phase of an oscillation or wave is the fraction of a complete cycle corresponding to an offset in the displacement from a specified reference point at time t= 0. Phase is a frequency domain -
Natural units
In physics, natural units are physical units of measurement based only on universal physical constants. For example, the elementary charge e is a natural unit of electric charge, and the speed of light c is -
Second harmonic generation
Second harmonic generation (SHG; also called frequency doubling) is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively "combined" to form new photons with twice the energy, and therefore twice -
Photoelectric effect
Photoelectric effect photoelectric effect is the process of emission of electron from the surface of metal when a photon of certain frequency is incident to a metal surface. Tthe electron committed is called photon electron. -
Double slit
The double-slit experiment in quantum mechanics is an experiment that demonstrates the inseparability of the wave and particle natures of light and other quantum particles. A coherent light source illuminates a thin plate with -
Diffraction
Diffraction is normally taken to refer to various phenomena which occur when a wave encounters an obstacle. It is described as the apparent bending of waves around small obstacles and the spreading out of waves -

Average air pressure adjusted to sea level: Average east-west wind: -
Liquid crystal
Liquid crystals are substances that exhibit a phase of matter that has properties between those of a conventional liquid, and those of a solid crystal. For instance, a liquid crystal (LC) may flow like a -
Scattering
Scattering is a general physical process whereby some forms of radiation, such as light, sound or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities -
Refractive index
The refractive index (or index of refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical -

Metamaterial
[1][2]A comparison of refraction in a left-handed metamaterial to that in a normal materialMain articles: Negative index metamaterials and Negative refraction Almost all materials encountered in optics, such as glass or -
Polarizer
A polarizer is a device that converts an unpolarized or mixed-polarization beam of electromagnetic waves (e.g., light) into a beam with a single polarization state (usually, a single linear polarization). Polarizers are used -
Reflection
Reflection is the change in direction of a wave front at an interface between two different media so that the wave front returns into the medium from which it originated. Common examples include the reflection -
Raman scattering
Raman scattering or the Raman effect (pronounced: Template:IPA —) is the inelastic scattering of a photon. Discovered By Dr. C.V. Raman in liquids and by Grigory Landsberg and Leonid Mandelstam in crystals. When light -
GREEK PHILOSOPHERS REJECT EINSTEIN
This paper was announced to many universities around the world (October 2013) By Prof.LEFTERIS KALIAMBOS ( Λευτέρης Καλιαμπός ) T. E. Institute of Larissa. Greece -
Elementary physics
Physics is all calculus. Trying to do physics without calculus is like trying to run a race on one leg. If the position of an object as a function of time is given by -
Gravitomagnetism
Gravitomagnetism (sometimes Gravitoelectromagnetism, abbreviated GEM), refers to a set of formal analogies between Maxwell's field equations and an approximation to the Einstein field equations for general relativity, valid under certain conditions. For instance, the -
HELIUM ATOM
[1]Added by Kaliambos Revolution in atoms by reviving the laws under the discovery of the electron spin (1925) showing a peripheral velocity greater than the speed of light -
Faraday effect
In physics, the Faraday effect or Faraday rotation is a magneto-optical phenomenon, or an interaction between light and a magnetic field in a dielectric material. The rotation of the plane of polarization is proportional
