Fiber optic transmission is based on the phenomenon of:
Open in App
Solution
The correct option is D Total internal reflection
In fiber optic transmission, light wave is passed as information from one end to another through a glass medium. A diagram of a typical optical fiber is shown in the attached figure. The inner region core has a higher refractive index than the cladding. Light is passed through the core and suffers total internal reflection on hitting the boundary of core. Transmission of data by optical fiber has been proved to be the most efficient mode of communication.
