Ruby flashed glass. Flashed glass, [1] or flash glass, is a type of glass [2] created by coating a colorless gather of glass with one [1] [3] [4] or more thin layers of colored glass. [5] This is done by placing a piece of melted glass of one color into another piece of melted glass of a different color and then blowing the glass. [1] [6]
The flash-lag effect. When a visual stimulus moves along a continuous trajectory, it may be seen ahead of its veridical position with respect to an unpredictable event such as a punctuate flash. This illusion tells us something important about the visual system: contrary to classical computers, neural activity travels at a relatively slow speed.
Flash-gas may be detected in the system by the observation of gas, bubbles or a foamy appearance of the liquid in the viewing glass in the liquid line. Depending on the location of the glass, this may also indicate an overwhelmed condenser, and the lack of these indicators at the glass does not definitely rule out flash-gas formation in the ...
The flash fully discharges before the arc can move away from the glass and fill the tube, causing excessive wear to the lamp. Simmer-voltage triggering is the least common method. In this technique, the capacitor voltage is not initially applied to the electrodes, but instead, a high voltage spark streamer is maintained between the electrodes.
A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4 ms + 1.0 ms = 3.4 ms, corresponding to a shutter speed of about 1 ⁄ 290 s. However some time is ...
There remain a few ambiguities about the effect. The current theory of triboluminescence—based upon crystallographic, spectroscopic, and other experimental evidence—is that upon fracture of asymmetrical materials, charge is separated. When the charges recombine, the electrical discharge ionizes the surrounding air, causing a flash of light.
Stained-glass example of chromostereopsis. It is commonly found in stained-glass, historically artists have been aware of this effect, using it to generate advancing or receding perspectives within the images. [11] Red–blue contrast was used in a portrait of Goethe
Video of the effect. The flashed face distortion effect is a visual illusion involving the fast-paced presentation of eye-aligned faces. [1] Faces appear grotesquely transformed while the viewer focuses on the cross midway between them. [2] [3] As with many scientific discoveries, the phenomenon was first observed by chance.
