Optics is the branch of physics that studies the behavior and properties of light. It encompasses a wide range of phenomena, including reflection, refraction, and dispersion. Understanding optics is essential for various applications, from designing lenses in glasses to developing lasers used in medical procedures. In addition to its practical applications, optics also plays a crucial role in scientific research. It helps us explore the universe through telescopes and understand the microscopic world with microscopes. The principles of optics are foundational in fields such as photography and fiber optics, making it a vital area of study in both science and technology.
