In our CBSE physics, light bends towards the normal upon entering glass with refractive index 1.5 because it slows down in the denser medium, changing direction as per Snell's law. But wah, in my tailoring, when I guide cloth under the needle, it often jolts and strays, unlike light which obeys so faithfully. This precision reminds me of my treadle machine's rhythm, where every stitch must be just right, much like light's unwavering path into glass.
