Light cannot shine through opaque materials at all. In fact, opaque materials absorb the light that shines on them. A little of the light is reflected back, though. Each object reflects some light waves of a certain color.

Does an opaque object transmit or reflect light?

Opaque materials do not allow transmission of light waves. In other words, we can't see through an opaque object. We can only see the surface because the light waves are re-emitted from the surface back to our eyes. ... When light waves are reflected, an object appears opaque.

Does opaque reflect the most light?

Opaque objects are those objects that light is able to pass through at all. They reflect most of the light falling on them.
