Mirror, mirror on the wall, how do light and matter mingle after all?
Scientists have known for a while that light has momentum and exerts force on whatever it hits. But because this momentum is so small, experiments haven't been able to observe exactly how it affects matter.
In search of answers, an international group of researchers turned to mirrors in a new study. "The mirror always tells the truth," Tomaž Požar, the lead author of the study and assistant professor in the department of mechanical engineering at the University of Ljubljana in Slovenia wrote in the playful analogy referencing "Snow White and the Seven Dwarfs" that he created and sent to Live Science.
