Wave-particle duality:
The principle of quantum mechanics that implies that light (and, indeed, all other subatomic particles) sometimes work as a wave, and sometime like a particle, based on the experiment you are performing. For example, low frequency electromagnetic radiation tends to act more such as a wave than a particle; high frequency electromagnetic radiation tends to act more such as a particle than a wave.
