Why objects reflect light instead of absorbing or transmitti

Click For Summary
When light interacts with an object, its behavior—whether it is absorbed, reflected, or transmitted—depends on the material's properties and the wavelength of the light. Some light is absorbed and converted into heat, while other light may be re-emitted in the same direction (transmitted) or at an angle (reflected). The specific interactions are influenced by the object's molecular structure and the energy levels of its electrons. Factors such as surface texture and the angle of incidence also play a role in determining the direction of emitted light. Understanding these principles is essential for comprehending light behavior in various materials.

So I've searched all over the internet for an explanation as to why when light of a certain wavelength hits an object, it absorbs it or reflects it. The best answer I've found is some light is absorbed and turned into heat, some is absorbed and re-emitted in the same direction (transmitted) and some is absorbed and emitted at an angle (reflected). My question is when light hits an object, what determines whether or not it is re-emitted and what determines which direction it is emitted in.
