Light is a form of electromagnetic radiation that plays a fundamental role in many processes. It travels in waves and can behave as both a particle and a wave, a concept known as wave-particle duality. The study of light encompasses topics like reflection, refraction, diffraction, and the speed of light in different mediums.
One of the most important discoveries in the physics of light is its speed—approximately 300,000 kilometers per second in a vacuum. Light’s behavior has led to advancements in technologies such as lasers, fiber optics, and even quantum computing, highlighting its crucial role in modern science.
