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..

. 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..

In the nineteenth century scientists saw enough evidence to prove that each element has its distinctive atom. But all tem atoms contain identical electrons. In spite of the fact that electrons carry negative charge, atoms as whole were found to be neutral. This led to the fact that atoms must conta..

Under certain experimental conditions, a beam of particles (for example, electrons ) can exhibit wavelike properties. Such matter waves are governed by the laws of quantum physics. The wavelength is inversely proportional to the momentum of the particles. These are also known a..

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&..
