In the photoelectric effect, what determines the maximum kinetic energy of the emitted electrons?
Answer and explanation
Correct answer: C. The frequency of the incident light
- Step 1: Each photon has energy hf, and an electron is emitted if hf exceeds the work function. Step 2. The leftover energy is the electron's kinetic energy. Answer: the frequency. Why not the others: intensity changes the number of electrons, not their energy.
