Question
Part A
When the surface of a metal is exposed to blue light, electrons are emitted. If the intensity of the blue light is increased, which of the following things will also increase?
When the surface of a metal is exposed to blue light, electrons are emitted. If the intensity of the blue light is increased, which of the following things will also increase?
the number of electrons ejected per second the work function of the metal the time lag between the onset of the absorption of light and the ejection of electrons the maximum kinetic energy of the ejected electrons all of the aboveExplanation / Answer
answer is part a ) the number of electrons ejected per second
K.E. of Electron = hf - work function
Changing intensity doesn't give photoelectrons more energy, it just increases the number ejected.
