We shine light of three different wavelengths—346 nm, 469 nm, and 624 nm—on a metal surface. The observations for each wavelength, labeled A, B, and C, are:. Observation A: No photoelectrons are observed. Observation B: Photoelectrons with a kinetic energy of 165 kJ/mol are observed Observation C: Photoelectrons with a kinetic energy of 53 kJ/mol are observed
