Dobereiner◦
BohrQuestion 2
With regard to the photoelectric effect, which of the following statements is incorrect?
◦
No electrons are emitted by a given metal below a specific threshold frequency of light.◦
Increasing the intensity of the light sufficiently can cause electrons to be emitted even though the light is below the threshold frequency.◦
For light with a frequency above the threshold frequency, the number of electrons emitted increases with increasing intensity of the light.◦
For light with a frequency above the threshold frequency, the kinetic energy of the emitted electrons increases linearly with the frequency of the light.◦
