... electron's momentum is ∆pelectron and certainly it is proportional to pphoton. Let us assume the constant of proportionality to be 1 in the present context. Thus, ∆pelectron = h/λ. Now the precision with which we can determine a distance is limited by the size of the wavelength λ of the light which ...

Some of the radioactivity was deflected to the positive plate; some of it was deflected to the negative plate; and the rest went through the magnetic field without deflection. Thus, there were three types of radioactivity: alpha particles (+), beta particles (-) and gamma r ...

Geiger–Marsden experiment
The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated. They deduced this by measuring how an alpha particle beam is scattered when it strikes a thin metal foil. The experiments were performed between 1908 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester.
