Question

consider the photoelectric effect experiment. in one experiment yellow light shines on a piece of potassium metal. a current is measured meaning electrons are ejected from the potassium metal. what would happen if the intensity of the yellow light increased

Answer 1

Explanation:

If the intensity of the yellow light increased, meaning more photons will strike the Potassium metal per unit area. This will cause more ejection of electrons from the metal and hence, the strength of current will also increase as we know that

I = Q/t, as the charge increase , the current will also increase.
