Applications of Polarized Light - Polaroids are used in sun glasses. They reduce the intensity and the glare by cutting down the horizontally polarized light. Polarized light is used in photo elastic stress analysis. For 3-D view, special type of glasses, which have po..

When a powerful beam of light is passed through a colloidal solution placed in a dark room, the path of the beam gets illuminated and appears as a glow in the colloidal solution. This is because of scattering of light by the colloidal particles...

Thus just as length has units like kilometer, meter, centimeter, millimeter etc., time also has units like year, month, day, hour etc. You must have been hearing quite a lot about the ending of the millennium and starting of the third millennium in the year 2001. Here we have larger units measuring..

Green house gases in the atmosphere behave much like the glass panes in a green house. Green houses are like small glass houses whose transparent glass roof and walls allow sunrays to pass through. It keeps the heat from escaping, thus allowing vegetables and flowers ..

A solar cooker contains a wooden box having thermocol lining from inside. A box made aluminium is placed inside the wooden box. The inner side of the aluminium box is painted black. The top is closed by a glass sheet. A plane mirror is fixed to the hinged lid. The box is closed such that ..

Green House Effect - Before green house effect is studied one needs to know what kind of radiation / sunshine we receive on earth. 'Sunshine' is a common man's term indicating all that we receive from sun. In a shallow perspective of common man, it may simply, mean light. But in a deep sc..

transmitted by T 1 and T 2 remain unaffected. However, when axes of the two crystals are at 90 0 to each other, light is completely cut off. This establishes that light waves are transverse in character. When unpolarised light is seen through a single crystal (polaroid), intensity of transmitted li..

Question: Global Warming - Climate An Introduction According to the National Academy of Sciences, the earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most ..
