Challenge Problems
Push your limits with advanced challenges
A metal has a work function of 3.0 eV. Calculate the maximum kinetic energy of emitted electrons when illuminated with light of frequency 6.0 × 10^14 Hz.
💡 Hint: Use the relations E = hf and KE = E - φ.
In an experiment, the stopping potential for photoelectrons emitted from a certain material is found to be 1.5 V. If the threshold frequency is 4 × 10^14 Hz, what is the maximum frequency of the light that could cause photoemission?
💡 Hint: Don’t forget the relationship between energy, voltage, and frequency.
