Photon polarization — is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave. Individual photons are completely polarized. Their polarization state can be linear or circular, or it can be elliptical, which is anywhere in … Wikipedia
Direct DNA damage — Direct DNA damage: The UV photon is directly absorbed by the DNA (left). One of the possible reactions from the excited state is the formation of a thymine thymine cyclobutane dimer (right). The direct DNA damage leads to sunburn, causing an… … Wikipedia
Direct realism — Direct realism, also known as naive realism or common sense realism, is a theory of perception that claims that the senses provide us with direct awareness of the external world. In contrast, indirect realism and representationalism claim that we … Wikipedia
Direct and indirect realism — Direct realism argues we perceive the world directly For representationalism in the arts, see Realism (visual arts). The question of direct or naïve realism, as opposed to indirect or representational realism, arises in the philosophy of… … Wikipedia
Photon mapping — In computer graphics, photon mapping is a two pass global illumination algorithm developed by Henrik Wann Jensen that solves the rendering equation. Rays from the light source and rays from the camera are traced independently until some… … Wikipedia
Direct and indirect band gaps — In semiconductor physics, the band gap of a semiconductor is always one of two types, a direct band gap or an indirect band gap. The band gap is called direct if the momentum of electrons and holes is the same in both the conduction band and the… … Wikipedia
Photon sphere — A photon sphere is a spherical region of space where gravity is strong enough that photons of light are forced to travel in orbits. The formula to find the radius for a circular photon orbit is: r=3GM/C2. Because of this equation photon spheres… … Wikipedia
Direct laser writing — A way to structure photosensitive materials in three dimensions is called Direct Laser Writing (DLW). Let s assume you take a laser operating at a wavelength where the exposed photo resist would usually be completely transparent due to the non… … Wikipedia
Direct bandgap — In semiconductor physics, a direct bandgap means that the minimum energy of the conduction band lies directly above the maximum energy of the valence band in momentum space. In a direct bandgap semiconductor, electrons at the conduction band… … Wikipedia
Two-photon physics — Two photon physics, also called gamma gamma physics, is a branch of particle physics for the interactions between two photons. If the energy in the center of mass system of the two photons is large enough, matter can be created.Fact|date=May… … Wikipedia
