quantum physics creation

According to Max Planck's Quantum theory, radiation is not continuous but is made up of tiny packets of energy called photons. However, this theory could not explain other optical phenomena. From all the above theories it is clear that certain optical phenomena can be explained clearly on..

The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is devoted to the st..

Generators are devices that produce electricity by converting mechanical energy into electrical energy. It works on the principle of 'electromagnetic induction' [Electromagnetic Induction is the creation of a voltage or current due to change in magnetic field]. Most of the electricit..

The principle of quantisation of electric charge states that "in nature there is a smallest amount of charge and all other charges are integral multiples of this smallest unit ". That is, if e is the minimum charge then the total charge on the body is equal to ne where n is an integer. This fact t..

n - neutron U - 235 Uranium Ba - Barium Kr - Krypton E - Energy Note : The number of neutrons released in a uncontrolled chain reaction of U-235 nuclei is given by 3 n where n = 1,2,3,..... A Schematic Diagram Showing Essential Steps in a Chain Reaction Based on Fission of U-2..

. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated with a definite amount of energy given by his mass-energy relationsh..

De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wave. According to Einstein relation E = mc 2 Where 'm' is the mass of the particle and 'c' = is..

. But, the actual result shows anomaly. This was not explained at that time. However, Planck propounded quantum theory in 1905. Einstein applied it to specific heat problem in 1907. Ultimately, Debye was successful in 1912, in fully explaining the thermal behavior of metals and non-metals..

Bohr improved upon Rutherford model postulating that electrons can revolve around the nucleus in certain discrete, non-radiating orbits, called stationary orbits, for which total angular momentum of revolving electron is an integral multiple of h / 2 p where h is Planck's constant. Where n = 1,2,3&..

Quantum Numbers - Schrodinger wave equation, when solved for hydrogen atom gives mathematical Y functions, which describe the allowed energy states in an atom. It is observed that physical meaningful solutions required three constants n, l and m, which are called quantum..
