Videoquang sai

In this lesson, we explore the technical term quang sai, which is the Vietnamese word for aberration in the fields of optics and physics. You will learn how this term describes the failure of light rays to converge at a single focal point, leading to image imperfections. We cover specific variations such as chromatic and spherical aberration, along with practical examples involving high-quality lenses and astronomical observations. Discover how to use this term correctly in scientific contexts and understand its relationship to refraction. Watch the lesson to master this essential vocabulary for science and photography.
