For a Certain Metal, Light of Frequency 7

question 6

Short Answer

For a certain metal, light of frequency 7.24 × 10^-14 Hz is just barely able to dislodge photoelectrons from the metal. (h = 6.626 × 10^-34 J ∙ s, 1 eV = 1.60 × 10^-19 J, e = 1.60 × 10^-19C)
(a) What will be the stopping potential if light of frequency 8.75 × 10^-14 Hz is shone on the metal?
(b) What is the work function (in electron-volts) of this metal?
