Asked by Mai
I need help on this homework problem and I do not understand how to work on it. Please help me with this problem.
The photoelectric work function of a metal is the minimum energy needed to eject an electron by irradiating the metal with light. For calcium, this work function equals 4.34X10^(-19)J. What is the minimum frequency of light required to observe the photoelectric effect in calcium?
