In a photoelectric experiment the straight-line plot of stopping potential V0 versus frequency ν cuts the frequency axis at 5×1014Hz. What does this intercept represent?
(a) Work function of the metal
(b) Threshold frequency of the metal
(c) Frequency at which the stopping potential is maximum
(d) Cut-off wavelength of the light used
