Monochromatic light is incident on a metal surface, and electrons are ejected. if the intensity of the light increases, what will happen to the ejection rate of the electrons? monochromatic light is incident on a metal surface, and electrons are ejected. if the intensity of the light increases, what will happen to the ejection rate of the electrons? the ejection rate will remain constant. changes in the ejection rate cannot be determined without additional information. the ejection rate will decrease. the ejection rate will increase.

The photoelectric effect is a phenomenon that consists of the emission of electrons by certain metals when a beam of light impacts on its surface.

For this phenomenon to occur, certain conditions must be met, such as when the photon collides with the electron, in order to "pull it" from the metal, the photon must have a minimum energy equal to the ionization energy of the atom, so that the electron can leave the influence of the nucleus.  

This is achieved with the adequate intensity of the incident radiation, which is related to the number of photons that impact the metal.

This means:

this means that the temperature of both substances will be equal

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
