  • question_answer
    Hydrogen atoms in a sample are excited to \[n=5\]  states and it is found that photons of all possible wavelengths are present in emission spectra. The minimum number of hydrogen atoms in the sample would be

    A)  5                                

    B)  6                  

    C)  10                              

    D)  infinite

    Correct Answer: B

    Solution :

     The wavelengths present in emission spectra are shown in the figure below \[(\Delta \phi ={{\phi }_{2}}-{{\phi }_{1}})\] one atom\[T=\frac{2\pi }{\omega }\] one atom  Remaining all by individual atoms.
