What Is Diffused Light?
To understand the nature of diffused light, we must first answer the question, “What is light?” Physicists define light as electromagnetic radiation. Traditional theory holds that light is a wave. Its amplitude gives the brightness, and the differing wavelengths make the different colors. Modern quantum theory says that particles of energy called photons make up light. The number of photons gives the brightness, and the energy in the photons creates its color. Both theories are correct. Light acts as both particle and wave. Simply put, light is that which enables us to see.
