Table 40.1 Work 11.) When 445 nm light strikes a certain metal surface, the stopping potential is 58% of that which results when 410nm light strikes the same metal. Based on this information and the table shown Functions of Selected identify the metal. Metals Metal (eV) Na 2.46 Al 4.08 Fe Cu 4.70 Zn 4.31 Ag 4.73 Pu 6.35 Pb Nate Values are typical for metals listed. Actual values may vary depending on whether the metal is a single crystal or polycrystalline. Valors may also depend the face from which dectrons are ejected from crystalline metals. Furthermore, different experimental procedures may produce differing values.
