Most other objects just reflect light. People experience light as having three features: color, brightness, and saturation. These three types of experiences come from three corresponding characteristics of light waves: The color or hue of light depends on its wavelength, the distance between the peaks of its waves. The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength. Yellow light tends to look brighter than reds or blues.
