Which of the following could Einstein's theory on the photoelectric effect explain that the wave theory could not explain?

Answer 1

A. electrons were ejected by incoming light
B. if the light intensity was increased, then the number of electrons ejected increased
C. the kinetic energy of photoelectrons was not related to the intensity of light
D. if the light intensity was decreased, then the number of ejected electrons decreased

Answer 2

i think its B

Answer 3

oops C

Answer 4

am i right @Michele_Laino ?

Answer 5

yes! it is C

Answer 6

ooh ok! thank you both!

Answer 7

since the kinetic energy of the emitted electrons depends on the frequency of the incident light
