When dim blue light shines on a piece of metal, electrons are ejected from its surface, but not when bright red light shines on the metal. Does this
phenomenon provide evidence for the wave model or the particle model of
light? Why?
A. The wave model, because increasing the brightness causes red
light to remove electrons
B. The particle model, because increasing the brightness causes red
light to remove electrons
C. The particle model, because only high-energy frequencies of light
can remove electrons
D. The wave model, because only high-energy frequencies of light
can bend around a barrier
