The threshold wavelength for cesium oxide is 7,000 angstroms, and that for tungsten is 2,730 angstroms. A chemistry student was testing cesium and tungsten and found that cesium emits light with a particular wavelength, but tungsten does not. What would be the most reasonable range of angstroms for the wavelength of the light that the student used? Explain your answer.​

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? a)visible b)ultraviolet c)infrared
