When infrared light of these frequencies strikes an object, the energy is reflected or transmitted. If the object is transparent, then the light waves are passed on to neighboring atoms through the bulk of the material and re-emitted on the opposite side of the object. Such frequencies of light waves are said to be transmitted. [10] [11]
Unlike transparent LCDs and OLEDs that requires integrated electronic modules to process visual signals or emit their own light, a passive transparent display uses a projector as the external light source to project images and videos onto a transparent medium embedded with resonance nanoparticles that selectively scatter the projected light.

Comparisons of 1. opacity, 2. translucency, and 3. transparency; behind each panel is a star. Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.
A zone plate consists of a set of concentric rings, known as Fresnel zones, which alternate between being opaque and transparent. Light hitting the zone plate will diffract around the opaque zones. The zones can be spaced so that the diffracted light constructively interferes at the desired focus, creating an image there.
The observation and study of optical phenomena such as rainbows and the aurora borealis offer many clues as to the nature of light. A transparent object allows light to transmit or pass through. Conversely, an opaque object does not allow light to transmit through and instead reflecting or absorbing the light it receives.
This optical arrangement provides the instructor with a number of advantages, among which are: the projector may be placed in front of the class; the brilliant light permits excellent screen visibility without darkening a room; the instructor may place transparent images on the horizontal stage or diagram extemporaneously on it without turning ...
In real life, Hoffmann, a former child actress, is the mom of Rosemary, 1. And given her long history in Hollywood, she, like Light, is deeply appreciative of her "Transparent" role -- not the ...
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used.
