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 1.6xx10^(16)Hz , the photoelectrons emitted had twice the kinetic energy as photoelectrons emitted when the same metal was irradiated with light of frequency 1.0xx10^(6)Hz . Calculate the threshold frequency (v_(0)) for the metal.

When a certain metal was irradiated with light of frequency 3.2 xx 10^(16)s^(-1) the photoelectrons emitted had three twice the KE as did photoelectrons emitted when the same metal was irradited with light of frequency 2.0 xx 10^(16)s^(-1) .Calculate the thereshold frequency of the metal

What a certain was metal was irradiatiobn with light of frequency 1.6 xx 10^(16) Hz the photoelectron emitted but the kinetic energy as the photoelectron emitted when the same metal was irradiation with light of frequency 1.0 xx 10^(16) Hz .Calculate the threslold frequency (v_(0)) for the metal

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

When a certain metal was irradiated with a light of 8.1 xx 10^(16)Hz frequency, the photoelectron emitted had 1.5 times the kinetic energy as the photoelectrons emitted when the same metal was irradiated with light 5.8 xx 10^(16)Hz frequency. If the same metal is irradiated with light of 3.846nm wave length, what will be the energy of the photoelectron emitted?
