Answer: reflected
A material is opaque when it does not allow light to pass through itself.
In other words:
When light illuminates an opaque object, no ray passes through it, as most of the light is reflected or absorbed by the object.
In this context, the main characteristic of this type of objects is that the color of the material depends on the light it absorbs. It means that depending on its chemical composition they can absorb certain wavelengths (colors) and reflect others.
Therefore, the color we see in an object is the light it reflects. For example, if we see a red table, this means that when light iluminates it, this table absorbed all the visible wavelengths, except the red, which is the light that is reflected and perceived by our eyes.
