The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect?

The light is made of different types of photon, which have different energy content depending on their frequency. When the photon falls on the solar panel, it needs to provide electron enough energy to escape the attraction from the nucleus of the atom. Hence, the energy of the photon should be high. So, the light with higher frequency is need for photoelectric effect because higher the frequency, higher will be the energy of the photon and it will lead to photoelectric effect.
