What is an optical fibre? A simple guide explaining its structure, working principle, and applications in modern communication and medical technology. Introduction Optical fibres represent one of the most important technological applications of total internal reflection. These are extremely thin strands of glass or plastic that form the backbone of modern communication systems and many
Understand “what is a prism?” and how the refraction through a prism takes place. Moreover, explore the dispersion of light through a prism. Introduction Light behaves in fascinating ways when it interacts with transparent materials. One of the most important optical devices used to study and manipulate light is the prism. Prisms are widely used
What is Total Internal Reflection? Discover how light behaves between different media and the science behind total internal reflection (TIR). Introduction TIR is one of the most remarkable phenomena in optics. It explains many interesting optical effects observed in nature and technology, including the formation of mirages on hot roads. However, to understand TIR, we
