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),…

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…

NEET PHYSICS-QUESTION ANSWER & SOLUTION (7)
QUESTION-1 The wave nature of electrons was experimentally verified by [A] Hertz [B] Einstein [C] Davisson and Germer [D] de Broglie ANSWER : ANSWER:[C] SOLUTION: From de Broglie hypothesis,the wavelength associated with an electron beam accelerated through 54 V should be 1.66 X 10-10 m. The tentatively estimated wavelength is near that assessed…
