Light from balmer series of hydrogen is able to eject photoelectron from a metal what can be the maximum work function of the metal?

Any radiation in the ultraviolet region of hydrogen spectrum is able to eject photoelectrons from a metal. What should be the maximum value of threshold frequency for the metal?

Light of wavelength 2000 Å can just eject electrons from a metal surface. Calculate the work function of the metal.

Wavelengths belonging to Balmer series lying in the range of 450 nm to 750 nm were used to eject photoelectrons from a metal surface whose work function is 2.0 eV. Find ( in eV ) the maximum kinetic energy of the emitted photoelectrons. ("Take hc = 1242 eV nm.")
