effects light transmission

There are many reactions, which are influenced by light. For example., photosynthesis and photography. Such reactions are known as photochemical reactions. Other examples are: Light supplies the necessary energy for the reaction to take place. Photographic films which a..

Attenuation - is undesirable because it reduces signal strength at the receiver. More serious, however, is distortion interference, and noise, which appear as alternations of the signal shape. Although such contaminations may occur at any point, the standard convention is to blame them entirely on ..

Light has varied effects on germinating seeds of different plants. Some seeds need light for germination, while in some seeds germination is hindered by light..

Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of light..

Doppler Effect in Light - Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of ..

Light energy influences almost all the aspects of plant life directly or indirectly. Thus, it controls plants structure, form, shape, physiology and growth, reproduction, development and local distributi..

Wavelength of light between 400 nm and 700 nm is most effective for photosynthesis. This light is called photosynthetically active radiation (PAR). Comparatively more photosynthesis occurs is red and blue regions though others have significant net photosynthesis. ..

Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may, in..

Light in some cases, for example in Salmon larvae, accelerates development where as in Mytilus larvae it retards ..
