Based on the research of albert einstein, what change would most likely result in stopping the emission of electrons from this metal? an increase in the intensity of the light a decrease in the intensity of the light the use of light that has a higher frequency the use of light that has a lower frequency

 The use of light that has a lower frequency

Explanation:  In order to stop the emission of electrons from the metal, the light used should be of lower frequency so that it wont be able to strike off the metal atom as effectively as it could.

When we use the light of lower frequency, the kinetic energy of the light decreases and thus it wont be able to emit much of the electrons from the metal surface.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

i just learnt this recently but i need to look through my notes again
