Light pulses are brief bursts of light energy that can be produced by various sources, such as lasers or light-emitting diodes (LEDs). These pulses can vary in duration and intensity, and they are often used in communication technologies, such as fiber optics, to transmit information over long distances. In scientific research, light pulses are utilized in techniques like time-resolved spectroscopy, which helps scientists study fast processes at the molecular level. By analyzing how materials respond to these short bursts of light, researchers can gain insights into chemical reactions and other dynamic phenomena.
