Question: An unknown metal is known to be either copper ( = 4.7 eV), uranium ( = 3.6 eV), zinc ( = 4.3 eV), beryllium (

An unknown metal is known to be either copper (φ = 4.7 eV), uranium (φ = 3.6 eV), zinc (φ = 4.3 eV), beryllium (φ = 5.0 eV), or platinum (φ = 6.1 eV). Using a photospectroscope, light of 118 nm wavelength is shined on the sample and electrons with 46801.8 cm-1 of kinetic energy are detected. What is the identity of the metal?
