💡TOTAL INTERNAL REFLECTION — A fascinating phenomenon of light!

When light travels from an optically denser medium to an optically rarer medium and the angle of incidence is greater than the critical angle, it undergoes Total Internal Reflection (TIR).✨

🔹 Optical fibres work on the principle of repeated Total Internal Reflection, allowing light signals to travel over long distances.

🔹 A mirage, commonly seen on hot roads and in deserts, is another interesting example involving refraction of light and Total Internal Reflection. 🌡️
