Final answer:
The dimension of color by which an object appears to reflect more or less of the incident light is called reflectivity. It varies from black to white for surface colors and from black to colorless for transparent volume colors. Reflectivity refers to the ability of an object to reflect light and affects how much light is absorbed or reflected by the object.
Step-by-step explanation:
The dimension of color by which an object appears to reflect more or less of the incident light is called reflectivity. It varies from black to white for surface colors and from black to colorless for transparent volume colors. Reflectivity refers to the ability of an object to reflect light and affects how much light is absorbed or reflected by the object.
For example, a black object has high absorbance of light and reflects very little, making it appear darker. On the other hand, a white object has low absorbance and reflects a significant amount of light, making it appear brighter.
Reflectivity can vary depending on the properties of the object's surface or volume, such as its texture, composition, and the type of material it is made of.
