why the light reflected by a object is not the object's colour but it is sunlight?for example , a black object absorb all colour so we can see it is 'black' but why it still reflect some light when we watch it/
Despite its name, a black object does not actually reflect light in the same way that a mirror or shiny object does. Instead, it reflects a small amount of light that is not absorbed by its surface.
A black object appears black because it absorbs all wavelengths of light, but it still reflects some light due to its surface texture. The rough surface of a black object causes light to scatter in multiple directions, resulting in a small amount of light being reflected back to our eyes.
The angle at which light hits a black object can influence how much light is reflected. When viewed from different angles, the light is reflected and scattered differently, making the object appear to be a different color. This phenomenon is known as specular reflection.
The texture of a black object can greatly impact how much light is reflected. A smooth surface will reflect more light and appear brighter, while a rough surface will reflect less light and appear darker. This is why a black object with a shiny surface may appear to be a different color compared to a black object with a matte surface.
The type and intensity of light source can affect how much light is reflected by a black object. For example, a black object may reflect more light under natural sunlight compared to artificial indoor lighting. Additionally, different wavelengths of light may be absorbed or reflected differently by the surface of a black object, causing variations in its appearance under different light sources.
