Laser ,Types and Use

Image
  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 th...

***Rainfall and Artificial Raifall***

Image
****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 upslo...

The Dancing with the stars but they seem higher than they actually appear and Atmospheric Refraction

Image
The stars seem higher than they actually appear-  as the light from a star enters the earth's atmosphere, it undergoes atmospheric refraction and bends towards the normal at position each time. The upper layers of the atmosphere are rarer than that lower layers. The apparent position of the stars slightly different from its actual position. The star appears slightly higher (above) than its actual position when viewed near the horizon. What is Atmospheric Refraction?                           - Earth can be considered to have consisted of layers of different densities, which acts as a rarer or denser medium with respect to one other. the refraction of light due to these layers is called atmospheric refraction. Advance Sunrise and Delayed Sunset-   The sun is visible to us about two minutes before the actual sunrise, and about two minutes after the actual sunset. this is because of atmospheric refraction....

Thrust and Pressure in daily life

Image
What is Pressure?                          - It is the force acting perpendicularly on a unit area of the object.             Pressure = Force/Area= Thrust/Area Note- We know that   the same force can produce different pressures depending on the area over which it acts.  - The same force acting on a smaller area exerts a large pressure while a force on a large area exerts small pressure. Applications in Daily life-   1.  Handles of bags are made broad                          - The handles of bags, suitcase, etc are made broad having more area so that small pressure is exerted on the hand. If we use thin handles, it may hurt our hand as pressure increase with less area. 2. The Tractors have broad tyres      - So that there is less pressure on the ground and the tyres do not sink in...
