Задача 50204.

Photoelectric threshold in rubidium is 0.81 microns. Determine the velocity of photoelectrons when irradiated rubidium monochromatic light with a wavelength of 0.4 microns. To determine retarding potential difference to the photocurrent ceased? As far as is necessary to change a retention potential difference by decreasing the wavelength of incident light by 2 nm?

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
