The maximum kinetic energy of the photoelectron is found to be 6.6x10^-19 J when the metal is irradiated with a radiation of frequency 2x10^15 Hz the threshold frequency of the metal is about

The threshold frequency for a photosensitive metal is 3.3 xx 10^(14) Hz . If a light of frequency 8.2 xx 10^(14)Hz is incident on this metal, the cut-off voltage for the photoelectron emission is nearly.

Statement I: Any light wave having frequency less than 4.8 xx 10^(14)Hz cannot emit photoelectrons from a metal surface having work function 2.0 eV Statement II: If the work function of a metal is W_(0) (in eV), then the maximum wavelength (in Å ) of the light capable of initiating photoelectric effect in the metal is given by lamda_("max") = (12400)/(W_(0))

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.

Work function of a metal is 2.3eV and on 1.0 cm^(2) area of that metal, a light of intensity 8.6 xx 10^(3) W.m^(-2) is incident. That intensity is distributed equally among the wavelength 4144 Å, 4972 Å and 6216 Å . If no ray is lost due to scattering and if each of the photons of proper energy can emit photoelectrons, what will be the number of photoelectrons emitted in 2 s? (h = 6.63 xx 10^(-34) J.s, 1eV = 1.6 xx 10^(-19)J)

The threshold frequency, v_(0) for a metal is 7.0xx10^(14)s^(-1) . Calculate the kinetic energy of an electron emitted, when radiation of frequency v=1.2xx10^(15)s^(-1) , strikes this metal.

The work function (phi) of some metal is listed below. The number of metals which will show photoelectric effect when light of 300 nm wavelength falls on the metal is :

When light incident on a metal has energy less than the work function of the metal, then no electron is emiited from the surface of the metal. Mathematically justify this statement.
