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…
