question is based on the video above (1.5 mins).
The main question is this, if photoelectrons are released based on the frequency of light that hits it, why is it that there is a large difference on the multimeter between when there is no filter, and when the blue filter is used (small wavelength=higher frequency). Shouldn't they be the same or almost the same? As the blue wavelength IS the smaller wavelength OF the light?
Anyone familiar with such experiment? It says in the video that the multimeter reads the energy of photoelectrons released by the light. Is this the kinetic energy of the electron?
If the multimeter reads the energy (in joules) of the photoelectrons, then amplitude should not be the affecting factor. Hence, the frequency/wavelength is the only factor, which leads to my question, shouldn't the readings of blue filter and no filter be close to each other? As blue is the smaller wavelength of the light
