[accordions autoHeight='true'] [accordion title="1. Particle Nature of Light"] A photon is a quantum of electromagnetic radiation. The energy of a photon is given by E=hf, where h is Planck's constant (6.63 10-34 J s) and f is its frequency. [/accordion] [accordion title="1.1 Photoelectric Effect"] The photoelectric effect is the emission of electrons from a metal surface when electromagnetic radiation of sufficiently high frequency

The Nucleus existence and size demonstrated using the Rutherford -scattering experiment. consists of nucleons (protons and neutrons) isotopes of an element share the same number of protons but different number of neutrons. Nuclear Reactions nuclear reactions involve two or more reactants. represented using the form: for a reaction that releases energy, mass-energy of reactants =
