The threshold frequency for a certain metal is 3.3 xx 10^14 Hz . If light of frequency 8.2 xx 10^14 Hz is incident on the metal, predict the cut-off voltage for the photoelectric emission.

Define the term work function of a metal. The threshold frequency of a metal is f_0 when the light of frequency 2f_0 is incident on the metal plate, the maximum velocity of electrons emitted is v_1 , when the frequency of the incident radiation is increased to 5f_0 , the maximum velocity of electrons emitted is v_2 . Find the ratio of v_1 and v_2 .

The thresold frequency for a certain metal is 3.3 xx 10^(14) Hz (Hertz). If the light of frequency 8.2 xx 10^(14) Hz (Hertz) is incident on the metal, find the cut off voltage for photoelectric emission.
