What is the working principle behind the transmission of optical signals through fiber optic cables?
A. Total internal reflection✓ Correct Answer
B. Interference
C. Dispersion
D. Scattering
💡 Solution & Explanation
Fiber optic communication relies on the principle of total internal reflection, where light rays traveling inside a high-refractive-index core bounce continuously off the cladding boundary without escaping. This mechanism allows high-speed data transmission over vast distances with minimal optical signal degradation.
