TORQUE The torque is a twisting force follows up on an article that produces revolution of an item and is given by the cross result(product) of position vector and the force vector. HOW DOES TORQUE WORK IN A VEHICLE ? Torque is made by the cylinders inside a motor as they respond all over on…

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),…

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…
