What evidence resulting from investigations into the photoelectric effect is consistent with the model of light subsequently proposed by Einstein?
- Photoelectrons were only ejected from a metal if the light was less than a specific wavelength.
- Increasing the intensity of light on a metal increased the maximum kinetic energy of the photoelectrons.
- If photons had sufficient energy to eject photoelectrons from a metal, the maximum kinetic energy was independent of the type of metal used.
- The probability of photoelectrons being emitted from a metal was proportional to the duration of exposure to light for any given wavelength used.
