Here is an indexed list of the work functions of a few common metalsr measured in electron volts: Caeaium 2.14eV Potassium 2.306V Sodium 2.758V Lithium 2.908V Calcium 2.87eV Copper 4.65eV Silver 4.268V Platinum 5.656V @QWPWP!' Light with a wavelength of 110nm is incident on a metal sun'ace. The most energetic electrons emitted from the surface are measured to have 9.166V of kinetic energy. Which of the metals in the table is the surface most likely to be made of? (Enter metal number) i l How many of the metals will eject electrons when light of wavelength 430nm is shined on them?| | Light with some unknown wavelength is incident on a piece of Silver. The most energetic electrons emitted from the Silver have 4.98V of kinetic energy. If the Silver is replaced with a piece of Caesum, what will be the maximum possible kinetic energy of the electrons emitted from this new surface?| l 61/
