kumar is producing the photoelectric effect by using red light. he wants to increase the energy of emitted electrons. based on the research of albert einstein, what is the best way for him to do this?\n○ increase the intensity of red light.\n○ decrease the intensity of red light.\n○ use a different colored light that has a higher frequency.\n○ use a different colored light that has a lower frequency.

Answer

Answer:

C. Use a different colored light that has a higher frequency.

Brief Explanations:

According to Einstein's photoelectric - effect theory, the energy of emitted electrons depends on the frequency of the incident light, not its intensity. Higher - frequency light has more energy per photon, which can increase the energy of emitted electrons.
