If energy is kept constant and intensity of photons is increased, will the threshold frequency be lowered?
I ask because I'd like to understand this graph - http://www.flickr.com/photos/coachrobbo/3909285882/
"lower intensity same frequency" causes stopping voltage to be lowered, thus threshold frequency is lowered. Why is this so? It would be really helpful if someone could add in an equation showing that a change in photon intensity alters threshold frequency.
