    From photoelectric equation
    hv + W + eV0 
    (where , W = work function)
    So hc/λ = W +  3eV0  ...(i)
    Also hc/2λ = W + eV0 
    ⇒ hc/λ = W +  3eV0  ...(i) 
    Subtracting Eq. (i) from Eq. (ii), we get 
    0 = W - eV0 
    ⇒ W = eV0 
    From Eq. (i), 

    The threshold wavelength is given by
