Explain the phenomenon of total internal reflection. What are necessary conditions to perform total internal reflection? Derive the formula for the refractive index of a medium in terms of the critical angle.
Total Internal Reflection (TIR) is a phenomenon in optics that occurs when a light wave traveling through a medium hits the boundary with another medium at an angle larger than a critical angle and is completely reflected back into the original medium. This means that no refraction occurs, and all the light is reflected. Necessary … Read more
