Question

For the photoelectric effect experiment, if uv light is shined on metal, resulting in a certain amount of current (electrons ejected) with certain amount of voltage created (the energy of the ejected electrons), then with an increase in intensity of light,

a) more current will flow (more electrons emitted, no change in voltage)

b) more voltage is created (ejected electrons have more energy, but current unchanged)

c) both current and voltage is increased

d) there is no change in current or voltage

e) none of these

Explanation / Answer

Option a). The emission of electrons increases when the intensity of light is higher since there is more energy available to release electrons.
