The optical properties of solids describe how electromagnetic radiation—ranging from infrared to ultraviolet—interacts with condensed matter. This field is essential for developing technologies like lasers, solar cells, and fiber optics.
When a solid absorbs energy and re-emits it as light (e.g., LED lights). Optical Properties of Solids
In the infrared range, light interacts directly with the vibrations of the crystal lattice (phonons). 5. Applications in Technology LED lights). In the infrared range
