Optical absorption is the process by which a material takes in light energy and transitions electrons to higher energy states, leading to a reduction in the intensity of transmitted light. This phenomenon is crucial in understanding the optical properties of materials and is widely used in applications like photovoltaics, spectroscopy, and optical sensors.

The optical properties of materials describe how they interact with light, including absorption, reflection, refraction, and transmission. These properties are determined by the material's electronic structure, chemical composition, and physical form, influencing applications in optics, photonics, and materials science.
