The Biomics on Instagram: "Bending Light, Shaping Vision” ✨💡 Refraction of Light Refraction is the bending of light as it transitions between different media, caused by a change in its speed. When light enters a denser medium, it bends towards the normal; when it moves into a less dense medium, it bends away from the normal. This explains why objects appear bent when viewed through water. 🌊 Critical Angle The critical angle is the point at which light moving from a denser to a less dense mediu
