I seriously have no clue what the answer would be, or else I wouldn't be on Yahoo Answers.

The quantized nature of the atom's energy levels requires that light:
A.Behaves like a wave.
B.Behaves like a particle.
C.Has different speeds when traveling through different materials.
D.Has an infinite speed.

I know, this is a homework question. But I really need help.

Thanks so much
