The photo electric threshold wavelength for a metal is `2750A^(@)` .The minimum energy of a photon that can produce photoelectric effect in the metal is ?

The photo electric threshold wavelength for a metal is 2750A^(0) . The minimum energy of a photon that can produce photoelectric effect in the metal is - - - - ev ?

The threshold frequency of metals 4 x 10^(14) s^(-1) The minimum energy which photons must possess to produce photoelectric effect with the metal is (h=6.6 xx 10^(-34) Js)

Photo-electric effect can be explained by

The best suitable metal for photo electric effect is

if the threshold wavelength for the given metal is 8 xx 10^(-6) m ,then What is the photoelectric work function for a metal ?

The photoelectric threshold of a certain metal is 3000A . If the radiation of 2000A is incident on the metal

The electrons are emitted in a photoelectric effect from a metal surface

The photo electric threshold wavelength of Tungsten is 2300 Å. The energy of the electrons ejected from the surface by ultraviolet light of wavelenghth 1800 Å is
