Light-induced reactions are chemical processes that occur when light energy is absorbed by molecules, leading to changes in their structure or reactivity. These reactions are fundamental in various natural phenomena, such as photosynthesis, where plants convert sunlight into chemical energy. In addition to photosynthesis, light-induced reactions are also utilized in technologies like solar cells and phototherapy. In these applications, specific wavelengths of light trigger reactions that can generate electricity or promote healing in tissues. Understanding these reactions is crucial for advancements in energy and medical fields.
