*) Black body radiation Planck’s law for the energy distribution for the radiation of a black body is: Stefan-Boltzmann’s law for the total power density can be derived from this: . Wien’s law for the maximum can also be derived from this: *)The Compton effect For the wavelength of scattered light, if light is considered to exist of particles, can be derived:  *)Electron diffraction Diffraction of electrons at a crystal can be explained...

 * Newton's law of universal gravitation expressess that the gravitational force between two object is the attractive force which its magnitude is directly proportional to the mass of each object and inversely proportional to the square of the distance between that centers. Mathematically it si written as follows. * The Value of universal gravitation constant (G) was first determined by Henry Cavendish by using Cavendish's torsion,...
