A) Light of frequency 9.13 x 10^14 s-1 shines on the surface of a certain metal, Metal X. if the ejected electrons have a velocity of 6.13x10^5 m/s, what is the work function (binding energy) of Metal X?

B) What is the longest wavelength of light (in nm) that can be used to eject electrons from the surface of Metal X?

C) A different metal, Metal Y, has smaller binding energy. If the same frequency of light from Part A is shined on Metal Y, will the ejected electrons move faster or slower than Metal X's ejected electrons? Explain your reasoning.
