With the world continuing to warm up, scientists are busy working on ways of cooling buildings without using vast amounts of energy – such as the record-breaking, ultra-white cooling ceramic composite that's been developed by researchers from the City...
I don’t have the vocabulary to explain, but when they say these are very reflective, they mean reflective in a different way than a mirror is reflective. A mirror does not just reflect, it also projects? Does that make sense? There would be no Death Ray with a white colored lense.
I think you’re describing diffusion versus the typical reflection where all light continues in the same direction. In this case the light diffuses, scattering in every direction. Because of that scattering, no specific point will receive a significant amount of energy to burn anything.
Thank you! What a great teaching image, too.
