Photochemistry

Photochemistry is the study of how light interacts with matter, particularly how light energy can cause chemical reactions. When light hits certain molecules, it can excite their electrons, leading to changes in their structure and properties. This process is essential in various natural phenomena, like photosynthesis, where plants convert light energy into chemical energy, and in technologies such as solar cells and photodynamic therapy for cancer treatment. Essentially, photochemistry bridges the gap between light and chemical transformations, revealing how energy from light can drive crucial biological and chemical processes.
