The term 'Virtual Light' was coined by scientist Stephen Beck to describe a form of instrumentation that produces optical sensations directly in the eye without the use of photons. [ 1 ] [ better source needed ] The novel was a finalist nominee for a Hugo Award , and shortlisted for the Locus Award in 1994.
An animation of how light rays can be gravitationally bent to form a photon sphere. A photon sphere [1] or photon circle [2] arises in a neighbourhood of the event horizon of a black hole where gravity is so strong that emitted photons will not just bend around the black hole but also return to the point where they were emitted from and consequently display boomerang-like properties. [2]
A ring flash is a circular light that is often operated with a camera lens in the center to take photographs. Unlike point light sources , a ring flash can illuminate a subject with minimal shadows by closely and evenly surrounding the optical axis of the camera lens.
As subsequent loops around the first ring bring the light to the resonance condition of the second ring, the two rings will be coupled together and the light will be passed into the second ring. By the same method, the light will then eventually be transferred into the bus output waveguide. Therefore, in order to transmit light through a double ...

The polarization of a virtual photon is determined by the direction of its momentum and its interaction with the charges that emit or absorb it. The range of polarizations for virtual photons can be compared to the range of colors for visible light, with each polarization corresponding to a specific orientation of the electric and magnetic fields.
