In a plot of photoelectric current versus anode potential, how does
1. The saturation current varies with anode potential for incident radiations of dissimilar frequencies but same intensity?
2. The stopping potential varies for incident radiations of different intensities but similar frequency?
3. Photoelectric current vary for different intensities but same frequency of incident radiations ?
