fuzzy blue lights

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. ..

When light passes through a substance or gas, a part of it is absorbed and the rest scattered away. The basic process in scattering is absorption of light by the molecules followed by re-radiation in different directions. The strength of scattering can be measured by the loss of..

Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. A large number of molecules are ..

It is the phenomenon of splitting of a beam of white light into its constituent colors on passing through prism. The order of colors from the lower end are violet, indigo, blue, green, yellow, orange and re..

. These bands are called interference fringes. The solid arcs represent the crests and the dotted arcs represent the troughs in the above diagram. When these arcs overlap, the (.) dots represent the maximum intensity i.e., constructive interference, whereas the (x) crosses represent the minimum int..

Blue Green Algae (BGA) - Blue green algae are autotrophic and nitrogen fixing organisms unlike heterotrophic and symbiotic nitrogen fixing microbes discussed above. They manufacture their food by photosynthesis, as they have chloroplasts. Hence, they can live independently. BGA ..

Green colour of the visible spectrum is ineffective in inducing flowering whereas blue colour induces poor flowering. The wavelength 580 nm to 680 nm in the red portion of the spectrum has been found to be most effective for inducing flowerin..

Sir Isaac Newton, while studying the images of heavenly bodies formed by a lens, found that the images were coloured at the edges. In 1665, to investigate this, he performed an experiment using a prism. Newton darkened his room at Trinity College, Cambridge and allowed a beam of sunlight to pass t..

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. If a source of light em..
