Dual nature of radiation and Matter

142290 From the figure describing photoelectric effect we may infer correctly that :

1 $\mathrm{Na}$ and $\mathrm{Al}$ both have the same threshold frequency
2 maximum kinetic energy for both the metals depend linearly on the frequency
3 the stopping potential are different for $\mathrm{Na}$ and Al for the same change in frequency
4 $\mathrm{Al}$ is a better photo sensitive material than $\mathrm{Na}$.
