Imagine shooting various colors of light at different kinds ofmetals. Depending on the work function of each metal, the lightwill or will not have enough energy to knock of an electron. (a)Which of the following metals will NOT emit electrons when visiblelight (with wavelengths of 380 nmto 700 nm) shines on them? (b) Ifvisible light can cause the metal to emit electrons, specific ifelectrons will be emitted when red (685 nm) light is used, green(532 nm) light is used and blue (473 nm) light is used. W0 is thework function for each metal. Cesium(W0= 2.1 eV) Rubidium(W0 = 2.3eV)
