The milky way is a Spiral Galaxy

The milky way is a Spiral Galaxy - After 75 years of research, radio, infrared and even x-ray telescopes have confirmed their existence, and found that the spiral cloud extends 100000 light-years (the diameter of the disk), with a thickness of 1000 light-years (the thickness of the disk). On this gorgeous disk, our tiny solar system lies on the inner edge of an arm, about 25000 light-years from the center.          ...

De broglie wavelength equation (De-Broglie equation )

De Broglie Wavelength Formula         In some situations, light behaves like a wave, while in others, it behaves like particles. The particles of light are called photons, and they can be thought of as both waves and particles. Louis de Broglie (1892-1987) developed a formula to relate this dual wave and particle behavior. It can also be applied to other particles, like electrons and protons. The formula relates the wavelength...

Home rothery's rules and regulations (physics)

Hume-Rothery rules:- HUME-ROTHERY'S RULES:-               In the course of an alloy development, it is frequently desirable to increase the strength of the alloy by adding a metal that will form a solid solution. In the choice of such alloying elements, a number of rules govern the for- mation of substitutional work of Hume-Rothery. Unfortunately, if an alloying element is chosen at random, intermediate...

CONTINUOUS CASTING PROCESS (Asarco Process)

Continuous casting process:- In Continuous casting process the forming die is an integral part of the furnace and thus there is no problem of controlling the flow of metal . The metal is fed by gravity into the mould from the furnace as it is continuously solidified and withdrawn by the rolls below . The die is water cooled and self lubricating and thus has excellent resistance to thermal shocks . The upper end of the die is in molten metal...
