Reflection is the opposite of absorption. Instead of being absorbed, some of the heat energy is bounced, or reflected off in the opposite direction. As this happens, the heat waves are unchanged, as is the object itself.
Objects which are good at absorption are as a result poor reflectors and vice versa. A mirror is an excellent reflector, while the blacktop found on a newly paved road is not.
Ever wonder why blacktop gets so hot in the summer? It is because the dark color makes it such a good absorber. Little of the heat energy from the Sun is reflected away. Instead it is absorbed, causing the road to become hotter and hotter.
