Gold foil experiment class 9

WebThe Alpha Particle Scattering Experiment They took a thin gold foil having a thickness of 2.1×10 -7 m and placed it in the centre of a rotatable detector made of zinc sulfide and a microscope. Then, they directed a beam of 5.5MeV alpha particles emitted from a radioactive source at the foil. WebDec 26, 2024 · What is the gold foil experiment?

WebFig. 4.2: Scattering of α-particles by a gold foil But, the α-particle scattering experiment gave totally unexpected results (Fig. 4.2). The following observations were made: (i) Most of the fast moving α-particles passed straight through the gold foil. (ii) Some of the α-particles were deflected by the foil by small angles. shreno limited glass division https://perituscoffee.com
