Photoelectric threshold of silver is `lamda=3800A`. Ultraviolet light of `lamda=2600A` is incident  of a silver surface. Calculate: a. the value of work function in joule and in eV.  b. maximum kinetic energy of the emitted photoelectrons.  c. the maximum velocity of the photoelectrons.  (Mass of the electrons`=9.11xx10^(-31)`).
