The number of photoelectrons emitted per unit time depends on (v gt v_(0))
The kinetic energy of electrons ejected by using light having frequency equal to threshold frequency (v_(0)) is:
The work functions of metals A and B are in the ratio 1 : 2 . If light of frequencies f and 2 f are incident on the surfaces of A and B respectively , the ratio of the maximum kinetic energy of photoelectrons emitted is ( f is greater than threshold frequency of A , 2f is greater than threshold frequency of B )
Photoelectric emission is observed from a metallic surface for frequencies v_(1) and v_(2) of the incident light. If the maximum value of kinetic energies of the photoelectrons emitted in the two cases are in the ratio n:1 then the threshold frequency of the metallic surface is
Calcualte the maximum kinetic energy of photoelectrons emitted where as light of freqency 2 xx 10^(16)Hz is irradiated on a metal surface with threshold frequency (v_(0)) equal to 8.68 xx10^(15)Hz .
Calculate the maximum kinetic energy of photoelectrons emitted when a light of freqency 2xx10 ^(16) Hz is irradiated on a metal surface with threshold frequency (v_0) equal to 8.68 xx 10^(15) Hz.
Photoelectric emission is observed from a surface for frequencies v_(1) and v_(2) of incident radiations (v_(1) gt v_(2)) . If the maximum kinetic energy of photoelectrons in the two cases are in the ratio of 2 : 1 then threshold frequency v_(0) is given by.
