. The energy received by the electrons helps it to escape from the surface of the metal and to do this the electron loses an amount of energy called as the work function of the surface of the metal ( f ). Therefore, if the energy received by the electron from photon is h u [equation (2)] and uses a..

Introduction - The goal of physics is to provide an understanding of nature. The science of physics was developed to explain our physical environment. Great Physicists like Galileo, Newton, and Einstein etc. framed laws to explain the various phenomena in nature. These..

Consider a spherical vessel having four cylindrical tubes A, B, C and D, each fitted with airtight frictionless piston, of area of cross-section 4a, 3a, 2a and a, respectively. When the vessel is filled with an incompressible liquid so that no air gap is left inside the vessel, a force 4 ..

It is found experimentally that the current I flowing through a conductor is directly proportional to the potential difference V across its ends, provided the physical conditions (temperature, mechanical strain, etc.,) remain constan..

The first experimental proof of the wave nature of electron was demonstrated in 1927 by two American physicists C.J Davison and L.H Germer. The basis of their experiment was that since the wavelength of an electron is of the order of spacing of atoms of a crystal, a beam of electrons shoe..
