Solve the all parts of following question given below:
Question: Light of wavelength 233 nm shines on a metal surface. 4.02 eV is required to eject an electron.
Part A: What is the kinetic energy of the fastest?
Part B: What is the kinetic energy of the slowest ejected electrons?
Part C: What is the stopping potential for this situation?
Part D: What is the cutoff wavelength for this metal?
I want help to determine the kinetic energy of the slowest ejected electrons.
