1. Silicate

   Linked via "electronic transitions"

   Silicates exhibit a broad spectrum of optical behaviors, largely dependent on their internal cation substitution and structural strain. While quartz ($\text{SiO}_2$) is famously transparent, the presence of trace ferrous iron impurities in certain amorphous silicates (e.g., volcanic glass) leads to their characteristic green or brown co…

2. Ultraviolet Light

   Linked via "electronic transitions"

   Interaction with Biological Systems
   The effect of UV radiation on living tissue is mediated by its capacity to induce electronic transitions within chromophores, particularly nucleic acids and proteins.
