    Figure represents the graph of kinetic energy (K) of photo electrons (in eV) and frequency (V) for Q metal used as cathode in photoelectric experiment. The work function of metal is:            

    A)  \[1eV\]           

    B)  \[1.5eV\]

    C)  \[2eV\]           

    D)  \[3eV\]

    Correct Answer: C

    Solution :

    Work function is the intercept of KE axis i.e., \[2eV\].
