The experimental study of the orotron tuned in the 78-100 GHz frequency range is carried out for two values of spherical mirror radii and three values of period to interaction space height ratios while a high voltage change from 15.3 to 24.5 kV was realised. The two-row periodic structure ...

Immensely popular in the 1970s, the plastic cartridge contained 16mm film which gave either 12 or 24 exposures. See 110 cameras: the rise and fall of little film format.360 camera A camera with two back to back 180+ degree fisheye lenses that can capture a full spherical view of the ...
When the electron transitions to its lowest energy state of n = 1 from n = 2 (where n is the main quantum number), the Lyman series in hydrogen spectra changes and ultraviolet emission lines are produced that's why the Lyman series lies in the UV region. The hydrogen atom experiences a...
A spotlight employing a single fresnel lens that produces a soft edged beam, and usually provided with a spherical reflector and a means to adjust the focus from spot to flood. Front Light Illumination from the general direction of the viewer(s). A luminaire that provides such illumination. Fr...
Such images have spherical sides. These types of photographs are often used in photos of real estate. Fast/Slow - you can use this term to describe the aperture of the lens. The faster the lens, the better the quality of the photo. Light bucket - it defines the photo shoot that is ...

The well-known approach for the calculation of the radiation pattern of a finite array from the scattering parameters between the array feeding ports (coupling coefficients) is connected to the theory of minimum-scattering antennas (MS antennas) by making use of spherical mode expansions. It is sh...
Spherulites– spherical crystalline body of radiating crystal fibers. Surface Resistivity– the resistance of a material between two opposite sides of a unit square of its surface. Syndiotactic– having a stereochemical regularity where the molecules can be described in terms of alternation of configurat...
The luminous intensity of a source expressed in candelas. Measured in an integrating sphere, Mean Spherical Candela is the total output of the source in lumens divided by 4pi steradians in a sphere. Candlepower (cp) Old definition of luminous intensity. One candlepower (cp) was the luminous...
