The wave-particle duality of light is a controversial topic in modern physics. In this context, this work highlights the ability of the wave-nature of light on its own to account for the conservation of energy in light-matter interaction. Two simple fundamental properties of light as wave are involved: its period and its power P. The power P depends only on the amplitude of the wave’s electric and magnetic fields (Poynting’s vector), and can easily be measured with a power sensor for visible and infrared lasers. The advantage of such a wave-based approach is that it unveils unexpected effects of light’s power P capable of explaining numerous results published in current scientific literature, of correlating phenomena otherwise considered as disjointed, and of making predictions on ways to employ the electromagnetic (EM) waves which so far are unexplored. In this framework, this work focuses on determining the magnitude of the time interval that, coupled with light’s power P, establishes the energy conserved in the exchange of energy between light and matter. To reach this goal, capacitors were excited with visible and IR lasers at variable average power P. As the result of combining experimental measurements and simulations based on the law of conservation of energy, it was found that the product of the period of the light by its power P fixes the magnitude of the energy conserved in light’s interaction with the capacitors. This finding highlights that the energy exchanged is defined in the time interval equal to the period of the light’s wave. The validity of the finding is shown to hold in light’s interaction with matter in general, e.g. in the photoelectric effect with x-rays, in the transfer of electrons between energy levels in semiconducting interfaces of field effect transistors, in the activation of photosynthetic reactions, and in the generation of action potentials in retinal ganglion cells to enable vision in vertebrates. Finally, the validity of the find

室内试验、数值模拟研究和有设计的外场综合试验是云降水物理和人工影响天气的三个重要支撑,在控制条件下对云雾和对催化剂的科学认识就直接关系到人工影响天气作业和试验的原理、催化方案设计和实施以及催化效果。碘化银焰剂是目前人工影响天气最主要的冷云催化剂类型,多年来我国的催化剂得到了长足的发展,成冰效率逐步提高,但是与国际先进水平并未进行过实质性的比较研究。在国家基金委项目支撑下,与世界人影强国俄罗斯开展联合研究,进行相同条件下两国碘化银催化剂的成冰性能对比研究。研究结果表明:我国目前人工影响天气外场实验和作业使用的碘化银焰剂成冰效率已经达到世界先进水平。同时,双方分别利用实验条件对碘化银成冰机理等特性、形态学和化学成分特性分析开展研究,取得一些非常有意义的结果。为认识目前我国冷云催化剂高效成冰性能的原因和进一步改进和优化配方提供有意义的指导方向。
