WHAT IS BINDING ENERGY PER NUCLEON? HOW IT IS RELATED TO THE STABILITY OF THE NUCLEUS?
NUCLEAR & ELECTROSTATIC FORCE: The nuclear force is a short-range force viable up to 2 to 3 fermi from a nucleon. The nuclear force that ties the nucleons together in a core, is a lot more noteworthy than the electrostatic force of attraction that ties an electron to an atom. NUCLEAR BINDING ENERGY: BINDING ENERGY…

HUYGENS WAVE THEORY- LAWS OF REFRACTION
WAVE THEORY: Christian Huygen, suggested the wave theory of light. Thomas Young, gave strong support to the wave theory of Christian Huygen. Fresnel, who showed that light is a transverse wave. Maxwell, on the basis of mathematical theory of magnetism showed that light is electromagnetic in nature. REFRACTION: Refraction is the phenomenon of bending of…
