Physics Assignement
complete assignment with clear solution and explanation
Weiss constant: The characteristic constant dependent on the substance, employed in computing the susceptibility of the paramagnetic materials.
Write a short note on diffuse reflection?
Coulomb's law (C. de Coulomb): The basic law for electrostatics, equivalent to Newton's law of universal gravitation. It defines that the force between two point charges is proportional to the arithmetical product of their respective
Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927): The experiment which conclusively proved the wave nature of electrons; diffraction patterns were examined by an electron beam penetrating into the nickel target.
Briefly define or explain the cause of Brownian motion?
Compton Effect (A.H. Compton; 1923): The effect which describes those photons (that is the quantum of electromagnetic radiation) has momentum. The photon fired at a stationary particle, like an electron, will communicate momentum to t
Dielectric is a material in which energy can be accumulated. Ideally, it is a non-conductor of electric charge like insulators, but an efficient supporter of electrostatic fields. The
Metre: meter; m: The basic SI unit of length, stated as the length of the path traveled by light in vacuum throughout a period of 1/299 792 458 s.
Fermat's principle: principle of least time (P. de Fermat): The principle, put onward by P. de Fermat that explains the path taken by a ray of light among any two points in a system is for all time the path which takes the least time.
1. Solve Laplace's equation for the electrical potential between two infinite parallel plates, which have a charge density per unit area -on one plate and a charge density per unit area -! on the second plate, and determine the electric field between the plates from t
