What surface texture reflects more infrared energy?

Polished surfaces are known for their ability to reflect more infrared energy due to their smooth and shiny characteristics. When a surface is polished, it minimizes scattering of incoming infrared radiation, thus allowing a greater proportion of that energy to be mirrored away effectively. This high reflectivity is particularly important in various applications, such as thermal imaging, where detecting heat signatures matters.

In contrast, surfaces that are rough, gritty, or have a matte finish tend to scatter infrared energy in various directions instead of reflecting it back uniformly. This scattering results in reduced overall reflection of thermal energy. Hence, while those textures might absorb more infrared radiation, they are not as effective in reflecting it as a polished surface is.
