| Abstract: | Though the discussion on a calculating problem of photoelectric effect the question to determine the value of stopping potential in consider contact potential diffrence is expounded. The meaning of the expression eVg = bv - between stopping potential Vg and the frequency of incident wave v is expounded too. |
