The Cross Ledge Light was a lighthouse on the north side of the ship channel in Delaware Bay off of Cumberland County, New Jersey on the East Coast of...

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum...

nanoparticles can have light scattering cross sections for particular frequencies that are much larger than their actual cross-sectional areas. In a gas...

photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the...

The Elbow of Cross Ledge Light was a lighthouse on the north side of the ship channel in Delaware Bay in Cumberland County, New Jersey, on the east coast...

The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light. A point source of light casts...

have no "all red" phase: the light turns green for cross traffic the instant the other light turns red. Many traffic light installations are fitted with...

The North and West London Light Railway (NWLLR), formerly known as the Brent Cross Railway, was a proposal for a light rail system in North and West London...

A cross is a geometrical figure consisting of two intersecting lines or bars, usually perpendicular to each other. The lines usually run vertically and...

roads and could create traffic delays as pedestrians crossed whenever they wanted. Off-the-shelf light-controlled systems were available but were too expensive...

that can be obtained as cross product of the light beam position (center of the beam) and its total linear momentum. A beam of light carries a linear momentum...

Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination...

cross (i.e. a horizontal cross extending to the edges, with the crossbar closer to the hoist than the fly) on a field of light blue. The Nordic cross...

future light cone of a given event will eventually grow to encompass more and more locations (in other words, the 3D sphere that represents the cross-section...

The True Cross is said to be the real cross that Jesus of Nazareth was crucified on, according to Christian tradition. It is related by numerous historical...

The extinction cross is an optical phenomenon that is seen when trying to extinguish a laser beam or non-planar white light using crossed polarizers. Ideally...

absorption, etc. (Note that light in this context is described as consisting of particles, i.e., photons.) Typical absorption cross section has units of cm2⋅molecule−1...

Inward light, Light of God, Light of Christ, Christ within, That of God, Spirit of God within us, Light within, and inner light are related phrases commonly...

receding from it, he concluded that light travels at a finite speed, and estimated that it takes light 22 minutes to cross the diameter of Earth's orbit. Christiaan...
