Is Geometrical Optics (GO) essential to fully appreciate the nature of light? I absolutely love Wave Optics (WO) and am currently studying it at the undergraduate level. However, GO feels more like an applied science, where I’m mostly dealing with the geometry of small angles. It doesn’t give me the same sense of fundamental physics, which makes me dread studying it. If I focus solely on WO and skip GO, would I be missing out on some physics?
