The online virtual experimental platform and the laboratory photoelectric effect method were used to measure Planck’s constant. Excel software was used for linear fitting, and Planck’s constant and errors were analyzed and calculated. It was found that the offline experimental value was better than the online virtual observed value. However, the error of the online virtual experiment value is also within the controllable range. In the particular current period of frequent epidemics or for schools lacking experimental instruments, it is also a perfect choice to use the virtual experiment platform to measure the relevant empirical data.
