The term "optical" relates to the science of light and vision. It encompasses the study of how light behaves, how it interacts with different materials, and how it is perceived by the human eye. This field includes various phenomena such as reflection, refraction, and dispersion, which are essential for understanding how we see the world around us. Optical devices, such as lenses, mirrors, and prisms, utilize these principles to manipulate light for various applications. For example, cameras use optical components to capture images, while microscopes allow us to see tiny details that are not visible to the naked eye. Understanding optical principles is crucial in fields like photography, medicine, and telecommunications.
