Question. An electron in the hydrogen atomjumps from excited staten to the ground state. The wavelength so emittedilluminates a photosensitive material having work function 2.75 eV. If the stopping potential of the photoelectron is 1 0 V, then the value of n isC(a)2(b) 3 (c) 4(d) 5 ...
Electrodynamics of the one-electron currents due to the circular orbital motion of the electron particle in the hydrogen atom has been examined. The motion is assumed to be induced by the time change of the magnetic field in the atom. A characteristic point is that the electric resistance ...
