The man who is credited with discovering that even individual light particles have wave characteristics is Albert Einstein. However, from the options you provided, the most relevant choice would be Max Planck. Planck is known for his work in quantum theory and introduced the concept of quantization of energy which laid the groundwork for understanding the dual nature of light, where light exhibits both particle-like and wave-like properties.

This concept paved the way for later developments, including Einstein's photoelectric effect research, which further established the particle qualities of light. While Newton and Taylor focused primarily on other aspects of light and Taylor is not typically associated with such foundational discoveries in light theory, Planck's work directly relates to the nature of light as being quantized and exhibiting both wave and particle characteristics. Thus, whilst Einstein made significant contributions to the understanding of light, from the provided choices, Planck is the most appropriate answer regarding wave characteristics of individual light particles.
