Noise can also be a weapon :long range acoustic device

Image
   Laser rays are a beam of rays moving in a straight line.  That is more powerful than ordinary rays.  Scientists have developed a long-range acoustic device that can also send sound waves across a beam in a straight line.  From the point at which any sound is produced it is spread all around by circular waves and slows down as it goes away.  The acoustic device produces sound and throws its waves in the same direction in a straight line in the shape of each other.  This device makes sound many times louder than our loudspeaker.  And does not slow down over long distances.  Would be surprised to know.  But this tool is useful to repel pirates at sea and terrorists hiding in inaccessible forests.  The human ear can tolerate noise up to a maximum of 120 decibels, so loud noise can damage the ears and brain.  The acoustic device can send a sound greater than 150 decibels over long distances.  This sound is unbearable to the ...

The science of hurricanes

Rain is a blessing for the living creatures of the earth but becomes destructive when it becomes a hurricane.  The heat of the sun does not fall uniformly on the earth.  The surface of the vast ocean gets warmer somewhere less and somewhere warmer.  As the hot air is thin and light, it goes to the sky, but instead the cold air is quickly absorbed.  The ebb and flow of the wind blows and the sea water evaporates.  Hurricanes form when this process is fast and tremendous.  Due to the wind it moves towards the shore.  Heavy rains and strong winds with thunderstorms in the hurricane cause many trees and houses to collapse and strong winds cause many trees and houses to collapse and damage families.  There are also some interesting things to know about hurricanes.  1. Most hurricanes occur in the United States.  Central America is called Tornado Alley, where 1,200 hurricanes, large and small, form every year.  2. When the wind speed is a...
