What is Total Internal Reflection (TIR)?
Total Internal Reflection Total Internal Reflection (TIR) is the principle of signal transmissions in optical fibers. The understanding of the critical angle is important to understand the TIR. Do you know at what time the incident angle is called the critical ...
