Achieve Question 6

[Liana Pooladi 3L]

On the Achieve homework assignment, I was able to figure out the first part of problem 6 by finding joules per photon from E=hv and subtracting by the given kinetic energy to figure out the work function. How would I go about solving the second part of the question that asks for the maximum number of electrons ejected from the metal?

Using the first part of the problem, you would assume that you are sending photons with the exact amount of energy required to emit an electron. Given that each photon has an energy equal to your answer in part 1, how many electrons can you send with 7.36e-7 J of energy. Essentially, you would divide 7.36e-7 J by your answer in part 1 to find the max number of photons you can send.
