Monochromatic light falls on a metal surface and electrons are ejected.If the intensity of the light is increased,what will happen to the ejection rate and maximum energy of the electrons?
A)greater rate;same maximum energy
B)same rate;greater maximum energy
C)greater rate;greater maximum energy
D)same rate;same maximum energy

Question

Quizplus · Accepted Answer

The ejection rate of electrons increases with the intensity of the light because more photons are hitting the surface, leading to more electrons being ejected. However, the maximum energy of the ejected electrons is determined by the frequency of the light, not its intensity, and remains the same as the intensity is increased.
