which makes Blue the only available light we see‚ and heres why! Theres alot of explainations when it comes to understanding why the sky is Blue. To understand why the Sky is Blue‚ you must first understand the basics. Such as the different Electromagnetic Waves‚ Colors of the Rainbow‚ Rayleigh Scattering‚ and the Different Light Spectrums. Color is simply defined as the sensation produced by the effect of light waves striking the retina of the eye. The color of something depends mainly on which

Life of Subhash Chandra Bose Subhash Chandra Bose was born into an affluent Bengali family on January 23‚ 1897 in Cuttack ‚ Orissa. Subhash’s public prosecutor father ensured that his son availed the best of education in eminent institutions such as Scottish Church College ‚ Calcutta and Fitzwilliam College at Cambridge University . In 1920‚ at the insistence of his parents‚ Bose appeared in the prestigious Indian Civil Service and secured the fourth place. During this period the civil disobedience

States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

SUMMARY Magnetic levitation is the process of levitating an object by exploiting magnetic fields. If the magnetic force of attraction is used‚ it is known as magnetic suspension. If magnetic repulsion is used‚ it is known as magnetic levitation. In the past‚ magnetic levitation was attempted by using permanent magnets. Earnshaw’s theorem however‚ proves that this is mathematically impossible. There exists no arrangement of static magnets of charges that can stably levitate an object. There

The considerable interest in computers and devices does shine light on some CMP topics and‚ now and then‚ discoveries such as high temperature superconductivity or Bose-Einstein condensation do get coverage‚ but anything involving Einstein is news.

The Tyndall effect‚ also known as Tyndall scattering‚ is light scattering by particles in a colloid or particles in a fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering‚ in that the intensity of the scattered light depends on the fourth power of the frequency‚ so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles‚ in particular two-stroke machines
