A metal surface is illuminated by light with a wavelength of 350 nm. The maximum kinetic energy of the emitted electrons is found to be 1.50 eV. What is the maximum electron kinetic energy if the same metal is illuminated by light with a wavelength of 250 nm?

Magnesium has a work function of 3.7 eV. A.) What is the longest wavelength of light that will release an electron from a magnesium surface?

Light of wavelength 340 nm, 600 nm and 680 nm is incident on a metal. Electrons are not emitted from the metal, which of the following is the most likely scenario.     The energy of the photon for 600 nm light corresponds to the work function of the material.     The energy of the photon for 680 nm light corresponds to the work function of the material.     The work function is less than any of these photon energies.     The work function is more than any of these photon energies.     The energy of the photon for 340 nm light corresponds to the work function of the material.

Violet light of wavelength 360 nm ejects electrons with a maximum kinetic energy of 0.89 eV from a certain metal. What is the work function of electrons to this metal, in electron volts?
