Question: Briefly describe the three absorption mechanisms in nonmetallic materials. Answer: The three absorption mechanisms in nonmetallic materials are Electron Transition, Vibration, and Synchrotron Radiation. Electron Transition involves the movement of electrons between energy levels within atoms, absorbing specific wavelengths of light in the process. Vibration, or vibrational absorption, involves the excitation of vibrational modes of atoms or molecules due to absorbed light, leading to a decrease in transmitted or reflected light intensity. Synchrotron Radiation occurs when charged particles emit radiation in a strong magnetic field, which can be absorbed by atoms or molecules in the material, affecting its absorption properties.
