Описание: The radiation emitted when an electron jumps from n=3 to n=2 orbit of hydrogen atom falls on a metal to produce photoelectrons. The electrons emitted from the metal surface with maximum kinetic energy are made to move perpendicular to a magnetic field of 1/320 T in a radius of 10^-3 m. Find
(a) the kinetic energy of the electrons,
(b) the work function of the metal and
(c) the wavelength of the radiation.
(Planck's constant h=6.62 × 10^-34Js )
