問題詳情

9. In photoelectric effect experiments, two different materials are illuminated by light of frequency f. Theinduced electrons passing a pair of parallel plates form a current that can be measured. The pair of platesare applied a voltage to decrease the current. The extinction voltage V is the minimal value of voltage suchthat the measured current becomes 0. Which of the following plots mostly represents the f-V relation?
(A)


(B)


(C)


(D)


(E)
