The "Physics of Color" refers to how light interacts with objects and how our eyes perceive different wavelengths of light. Light is made up of various wavelengths, and each wavelength corresponds to a different color. When light hits an object, some wavelengths are absorbed while others are reflected. The colors we see are determined by the wavelengths that are reflected into our eyes. Our eyes contain cells called cones that are sensitive to different wavelengths of light. There are three types of cones, each responding to red, green, or blue light. The brain processes the signals from these cones to create the full spectrum of colors we perceive. This combination of light and perception is fundamental to understanding how we experience color in the world around us.
