Description

Zinc bead radius of 2.0 cm is irradiated with photons of ultraviolet radiation with a wavelength of 0.20 microns. Determine the electron work function of zinc, photoelectric threshold, the maximum speed of the emitted electrons, de Broglie wavelength corresponding to the emitted electrons, the retarding potential value at which stops the photoelectric effect, the number of photons which thus gets into a ball, if we assume that each photon knocks out an electron. The potential of the work function of zinc to 3.74 V.
