What is a colour(or) What is definition of colour at physics?Is black really a colour

Colour:-Colour is  a fixed wavelength of light coming out from a body
Do you know the substance what we call as colour is simply a substance that changes or tends to change the wavelength
of light such that its look like the specified colour
Black:-Black is not a colour.It is a light having improper wavelengths or a light whose wavelengths are mixed

WHY SKY APPEARS IN BLUE DURING DAY AND IN BLACK DURING NIGHT?
Reasons:-
1. You know that sky is covered by clouds.They contain microscopic dust particles and small water particles.When light passes through water and dust particles it gets dispersed(as it has a property of dispersion).water has a property of giving out more blue light.
2.At night there will be no light and there will be no dispersion.So sky appears in black colour

Do you know pilots cannot see blue colur sky as they are top of clouds even during day time

Amazing facts

Do you know an intresting fact about rainbow?
Rainbow is spherical in shape.But we can see it only in semispherical shape.The other part is covered by indigo colour.Indigo colour in sky will visible to us.But astronauts can see a spherical rainbow

Unknown inventors

Richard H.Frienkel

Richard H. Frenkiel is an American engineer, known for development of cellular telephone networks.
Born (March 4, 1943) in Brooklyn, New York, Frenkiel earned a bachelor's degree in mechanical engineering at Tufts University and earned a master's degree at Rutgers University in 1965. Beginning in 1963, he worked for Bell Labs where he first designed recorded announcement machines. In late 1965, he was invited to get involved in the early planning of cellular telephone systems along with Bell Labs engineers Joel S. Engel and Philip T. Porter, an effort which lasted more than sixteen years. They worked on cell geometry, vehicle locating, and call handoff. In 1971 Porter, Engel, and Frenkiel authored a cellular system feasibility study and proposal that was submitted to the Federal Communications Commission (FCC)

New inventions

1.New hybrid car

One of the most exciting contraptions that you may encounter for 2011 is flying cars.  MIT students from the Department of Aeronautics and Astronautics have actually succeeded in creating and flying a winged car. This is said to be the wave of the future. The company that is reported to release the space ship looking  cars is called Terrafugia. So be sure to look to the skies in 2011

A new era of science has beenstarted in the field of physics by the inventions of galileo.His inventions has been proved later though he had been proclaimed true. So we should be thankfull to him.
