Dr Sushil KumarTo determine the Planck’s constant, in this experiment we use 3-4 different colors light emitting diodes. We observe the stopping potential of each LED and plot it with the frequency or wavelength to calculate the value of Planck’s constant. The quiz is helpful to you […]

Dr Sushil KumarThe photo electric effect is a phenomenon in which electrons eject from the material surface when light falls on it. The electrons which emitted in this process are photoelectrons. For the photoelectric emission process alkali metals are generally use. These are lithium, sodium, potassium, rubidium […]
Dr Sushil KumarAtom is neutral, consists electrons revolving around nucleus at its center. This experiment was performed in 1914 by German scientists James Franck and Gustav Hertz. Atom is Objective of the Franck-Hertz Experiment The purpose of this experiment is to determine the discrete nature of the […]
Dr Sushil KumarIntroduction to Geiger Counter The Geiger counter is used in this experiment, having mainly geiger muller tube that detect the particles. The radioactive source for the experiment is Cesium-137. The Geiger Muller tube was invented by the German physicists Hans Geiger and Walther Muller in […]
