A metal is irradiated with light of frequency `3.2xx10^(16)Hz`. The ejected photoelectron has kinetic energy `(3)/(4)`the of energy of absorbed photon. The threshold frequency orf the metal would be :

If a metal is irradiated with light of frequency 3 xx 10^(19) sec^(-1) , electron is emitted with kinetic energy of 6.625 xx 10^(-15)J . The threshold frequency of the metal is

If a metal is irradiated with light of frequency 3 xx 10^(19) sec^(-1) , electron is emitted with kinetic energy of 6.625 xx 10^(-15)J . The threshold frequency of the metal is

If a metal is irradiated with light of frequency 3 xx 10^(19) sec^(-1) , electron is emitted with kinetic energy of 6.625 xx 10^(-15)J . The threshold frequency of the metal is

When a certain metal was irradiated with light frequency 1.6xx10^(16) Hz , the photo electrons emitted had twice the kinetic energy as did photoelectrons emitted with frequency 1xx10^(16)Hz when the same metal was irradiated with light then threshold frequency x xx 10^(15) Hz . Find ''x''.

When a certain metal was irradiated with light of frequency 40xx10^(16) s^(-1) , the photoelectrons emitted had four times kinetic energy as the kinetic energy of photoelectrons emitted when the same metal was irradiated with light of frequency 2.0 xx 10^(16) s^(-1) . the trhreshold frequency ( v_(0) ) of the metal in s^(-1) is

When a certain metal was irradiated with light of frequency 4.0 xx 10^(19)s^(-1) the photoelectrons emitted had three times the kinetic energy as the kinetic energy of photoelectrons emitted when the metal was irradited with light of frequency 2.0 xx 10^(16) s^(-1) .Calculate the critical frequency (v_(0)) of the metal
