| Abstract: | In doing photoelectric effect experiment to measure Planck constant,the diaphragm and the filter should be mounted on the phototube camera obscura on the optical input.By repeated measurements of data,an analysis is made as for whether and how much the aperture size will affect the measurement of the cut-off voltage U0. |
