We shine light of three different wavelengths—325 nm, 455 nm, and 632 nm —on a metal surface. We record the following observations for each wavelength, labeled A, B, and C: Observation A: No photoelectrons were observed. Observation B: Photoelectrons with a kinetic energy of 155 kJ/mol were observed Observation C: Photoelectrons with a kinetic energy of 51 kJ/mol were observed
