Question

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? Increase the intensity of red light. Decrease the intensity of red light. Use a different colored light that has a higher frequency. Use a different colored light that has a lower frequency.

Answer 1

long story short it's C !

Step-by-step explanation:

I got it right :)

Answer 2

Based on the research of Albert Einstein the best way to increase energy of emitted electrons when using red light is to use a different colored light that has a higher frequency. Albert Einstein has proved that the energy of the emitted electrons depends only on the frequency of the incident light, and not on the light intensity.
