Final answer:
Light is an example of wave-particle duality, where it exhibits both wave and particle properties. While many light phenomena can be explained using either model, certain phenomena cannot be explained by only considering light as a wave. This led to the development of quantum mechanics to incorporate both the wave and particle aspects of light.
Step-by-step explanation:
Light is an example of wave-particle duality, which means it exhibits properties of both waves and particles. While many light phenomena can be explained using either the wave or particle model, certain phenomena, such as interference patterns and the photoelectric effect, cannot be explained by just one model. This led to the development of quantum mechanics, a more complex theory that incorporates both wave and particle aspects of light. Therefore, there are certain aspects of light that cannot be explained if it is considered solely as a wave.
