What is the effect on the velocity of the emitted photoelectrons if the wavelength of the incident light is decreased?

Light rays of wavelength lambda and lambda/2 are incident on a a photosensitive metal surface, IF the maximum kinetic energy of the emitted photoelectrons from the metal surface in 2nd case be 3 times the maximum kinetic energy of emitted photoelectrons in the 1st case then determine the work function of the metal.

Above the threshold wavelength for a metal surface, even a light of low intensity can emit photoelctrons. Is the statement true?

Work function of a metal surface is 2eV. Maximum kinetic energy of photoelectrons emitted from the surface for incidence of light of wavelength 4140 Å is 1eV. What is the threshold wavelength of radiation for that surface?
