When red light shines on a piece of metal, no electrons are released. when the red light is slowly changed to shorter-wavelength light (basically progressing through the rainbow), nothing happens until yellow light shines on the metal, at which point electrons are released from the metal. if this metal is replaced with a metal having a higher work function, which light would have the best chance of releasing electrons from the metal? if this metal is replaced with a metal having a higher work function, which light would have the best chance of releasing electrons from the metal? and explain why and list any equations if there are any.
a. red.
b. blue.
c. yellow would still work fine.
d. we need to know more about the metals involved.
