                     Why is the Sky Blue?        This is the one of those questions which four year old's ask all the time that what makes the sky blue.To understand that we have to look one thing which makes blue to sky is atmosphere.The atmosphere is mixture of gas molecules,water and dust that surrounding the earth.The light from the sun is scattered by the atmosphere in all direction.The white light that coming from the sun is really made up of all colors of the rainbow.Between all these seven colors blue light scattered more than the red light because of it's shorter wavelength.        Light travel from the sun in the form of wave that similar to the wave of ocean. Some are close together and others are further far. Distance of each same peak of wave is called wavelength. When all the wavelength travel together light looks white to our eyes. If we break the light of su...

        Why hurricanes spin anti-clockwise direction ?       In the tropical region due to high intensity of sunlight high temperature and  low pressure is created in the atmospheric air.This air goes to the upper region of atmosphere and empty space is created in this region.To fulfill this space cool air comes from cooled region and collides turbulently which leads to formation of  hurricanes .Hurricanes are one of the worst natural disasters on the planet. They lead to devastating casualties, and take a significant toll on properties each and every year. Counterclockwise hurricanes are tropical storms that form in the northern hemisphere .Storms in southern hemisphere like cyclone rotates clockwise.It has to do with something called the Coriolis effect.The Coriolis effect is a result of earth's rotation. The area around the equator rotates faster than the poles.This causes water and air to curve as they move north or south. In nort...

              How a refrigerator works?           All of we have seen a refrigerator.Its invention has changed the way we live.Refrigerator has made it possible for everyone to preserve food for days together.But have we wondered that, how a refrigerator works to maintain cold its inside? Lets know that how it works and about its parts.         A thermally insulated component that transfers heat from the inside of the fridge to its external environment so that the inside cooled to a temperature below the room temperature is called refrigerator. It mainly consists of a few key components that play a vital role in refrigeration process.                           1. Compressor                           2. Condenser               ...

                                Types of light         I n our entire solar system only sun emits light. Really strong intense light or radiation called electromagnetic radiation or EMR.The radiation is called electromagnetic because it contains both electric and magnetic property. EMR is a large family consisting of seven members known as electromagnetic spectrum. One particular family member which lies in the middle of spectrum falls on earth and which are eye detect are called visible light or visible spectrum. It is so small that if we consider entire electromagnetic spectrum to be around 2500 miles the visible fraction is just 1 inch. It is within this inch that we live world of natural and extraordinary high different color. The other type of electromagnetic radiation are also called light but not visible light. So automatically they are considered as to be invisible lig...
