When a metal surface is irradiated with light of frequency x {\Hz}, the kinetic energy of emitted photoelectrons is z {\J}. When the same metal is irradiated with light of frequency y {\Hz}, the kinetic energy of emitted electrons is \frac{ {\z}}{3} {\J}. What is the threshold frequency (in Hz) of metal?
