JEE Main & Advanced Chemistry Structure of Atom Question Bank Dual nature of electron

  • question_answer In which one of the following pairs of experimental observations and phenomenon does the experimental observation correctly account for phenomenon                                         [AIIMS 1983]

    A)  Experimental observation -\[X\]-ray spectra                                   Phenomenon-Charge on the nucleus

    B)  Experimental observation -\[\alpha \]-particle scattering                          Phenomenon-Quantized electron orbit

    C)  Experimental observation -Emission spectra                   Phenomenon-The quantization of energy

    D)  Experimental observation -The photoelectric effect    Phenomenon-The nuclear atom

    Correct Answer: C

    Solution :

                    Emission spectra of different \[\lambda \] accounts for quantisation of energy.
