Discuss the application of wave optics in fibre... - SS2 Physics Optics - Wave Optics Question

Fibre optics communication relies on the principle of total internal reflection. Light signals are transmitted through thin strands of optical fibres made of high-quality glass or plastic materials. When light enters the fibre at an angle greater than the critical angle, it undergoes total internal reflection and propagates along the fibre by continuously reflecting off the inner walls. This phenomenon allows for efficient transmission of light signals over long distances without significant loss of signal strength. The essay should also discuss the advantages of fibre optics communication, such as high bandwidth, low signal degradation, and immunity to electromagnetic interference.
