  LASER :-                    LASER is an acronym of  Light Amplification by stimulated emission of Radiation. It is an optical device which produces an intensive beam of highly coherent, Monochromatic light[ Electromagnetic radiation, especially visible radiation, of only one frequency or wavelength]. It can travel over great distance without spread.   LASER LIGHT :-                                   1. It is very different than normal light and contains only one specific wavelength of light.                                 2. A laser light has very tight beam and is very strong and concentrated.                                 3. A laser light can go to the moon and then come back to the earth without any appreciable change in intensity.                                  4. The light released is monochromatic (consists of only one wavelength) and coherent.  LIPS ( LASER Induced Plasma Spectroscopy) :- It is based on plasma formation on temperature basis, the material absorbs all th

****Mawsynram[INDIA]**** (A village in the state of Meghalaya(one of the seven sisters in north-eastern India) [Based on the data of a recent few decades, it appears to be the wettest place in the world or the place with the highest average annual rainfall.  Mawsynram  receives over 10,000 millimetres of rain in an average year, and the vast majority of the rain it gets falls during the monsoon months.] Reason of Rainfall-                              The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as  weather fronts . If enough moisture and upward motion are present, precipitation falls from   clouds (those with strong upward vertical motion) such  cumulonimbus   (thunder clouds) which can organize into narrow rainbands . In mountainous areas, heavy precipitation is possible where upslope flow   is maximized within windward  sides of the terrain  at  elevation which forces moist air to co
