Challenge Problems
Push your limits with advanced challenges
A photon of light with frequency of 6 x 10^14 Hz strikes a metal surface with a work function of 2.5 eV. Calculate the maximum kinetic energy of the emitted electrons.
💡 Hint: Use the photoelectric equation and remember to convert eV to joules.
If the minimum work function of a material is 4 eV, what is the threshold frequency required to emit electrons?
💡 Hint: Evaluate how much energy is translated into frequency.
