| 释义 | optics (once / 1778 pages) n Scientists who study the physics of light are experts in optics. The field of optics includes light's physical attributes and the way our eyes detect it. If you learn about optics in a physics class, you'll spend some time learning about vision, which involves our eyes' ability to focus and reflect light — to see, in other words. Other aspects of optics include properties like reflection, refraction, and various ways light interacts with matter. Informally, optics is also used to mean "political spin," or the way the public perceives what politicians say and do, and how politicians tailor their actions to be viewed in specific ways.
