👉 Autoexcitation is a phenomenon in physics where light or other electromagnetic waves are refracted due to the motion of matter, such as atoms and molecules. When a wave interacts with an object that has a high enough frequency relative to its wavelength (i.e., it is moving fast), the object can bend the wave's path, causing it to return to its original position after reflection. This phenomenon is particularly common in materials like glass, which undergoes a phase change when heated or compressed. The process
