So when light sources have long wavelengths/ low frequencies then light cannot eject electrons? This is even true when you change the intensity of the light?

Basically yeah. It always depends on the threshold frequency; any frequency less that the threshold value won't be enough energy to eject the electron.

Yes. A frequency that is less than the threshold value is not enough energy for the election to eject. It's true for all intensities.

Yes. We learned that it was unexpected, but changing to higher intensity light did not eject electrons, but changing the frequency of light emitted did. This demonstrates the particle-like qualities of light.

Yes, which shows the particle-like quality of light.

Yes because the intensity of the light on changes the amplitude of the waves but does not give it enough energy to eject electrons.
