The work function of metal is 1 eV . Light of wavelength 3000 Å is incident on this metal surface . The velocity of emitted photo - electrons will be
Light of wavelength 4000Å is allowed to fall on a metal surface having work function 2 eV. The maximum velocity of the emitted electrons is (h=6.6xx10^(-34)Js)
Light of wavelength 2000Å is incident on a metal surface of work function 3.0 eV. Find the minimum and maximum kinetic energy of the photoelectrons.
Light of waelength 4000Å is incident on a metal plate with work function 2eV. The max. K.E. of the photoelectrons is
Light of wavelength 500 nm is incident on a metal with work function 2.28 eV . The de Broglie wavelength of the emitted electron is
When the light of wavelength 400 nm is incident on a metal surface of work function 2.3 eV , photoelectrons are emitted. A fasted photoelectron combines with a He^(2+) ion to form He^(+) ion in its third excited state and a photon is emitted in this process. Then the energy of the photon emitted during combination is
The work function of a metal is 2.5 eV. Light of wavelength 3600 Å is incident on this metal surface. The velocity of emitted photoelectrons will be
