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…

DAVISSON AND GERMER EXPERIMENT & De-BROGLIE’S RELATION/PHYSICS
DAVISSON AND GERMER EXPERIMENT: Davisson and Germer terminated a finely collimated light emission (beam of electrons) at the essence of the crystalline nickel target. The angular dependence of the reflected electron intensity as estimated to have a similar diffraction pattern as those anticipated by Bragg for X- ray beams. The sped up voltage is fluctuated(varied),…

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…

INTERFERENCE OF LIGHT/PHYSICS
INTERFERENCE OF LIGHT: The phenomenon by which intensity is redistributed when two light waves from two coherent sources superpose each other. *INTERFERENCE OF LIGHT is an example for the Wave nature of light. *CONSTRUCTIVE : When the two waves are in phase. *DESTRUCTIVE: When the to waves are out of phase. COHERENT SOURCES: S1 and…

PHOTOELECTRIC EFFECT
The peculiarity by which electrons are transmitted from a metal surface, when adequately high frequency electromagnetic radiations are permitted to incident on it. MAIN PARTS: Vacuum tube transparent to ultraviolet light. PHOTONS: Light beam is a discrete energy packets. PHOTOELECTRIC EFFECT:- EXPLANATION # Photoelectric effect is the consequence of connection of two particles. One is…
