Low-E coatings are placed on house windows because
A) the coating prevents convective heat transfer.
B) radiative heat transfer is a big problem for clear windows but the Low - E coating reflects the visible light.
C) radiative heat transfer is a big problem for clear windows but the Low - E coating reflects ultraviolet light.
D) radiative heat transfer is a big problem for clear windows but the Low - E coating reflects infrared light.

Question

Quizplus · Accepted Answer

Low-E (low-emissivity) coatings are applied to windows to minimize the amount of infrared and ultraviolet light that can pass through glass without compromising the amount of visible light that is transmitted. These coatings reflect infrared light, helping to keep heat inside during the winter and outside during the summer, thus addressing the issue of radiative heat transfer through windows.
