WebReflection is when light reflects off of a surface, such as a mirror, or off of polished or wet surfaces. If a surface is reflective, then IR bounces off of it, making it more relatively cool. It is unable to absorb as much light. Transmission is when light passes through an object, like sunlight through a window.
