Question

What is Optical Fiber and write principle with which light passes through it?​

Answer 1

Answer:

Explanation:

Principle of Optical Fiber

When light travels through the core, it travels very slowly and then transmitted to the cladding. The cladding further reflects light back to the core, and so on. When light from the core strikes the border of the cladding, with an angle less than 90°, it bounces off.

Answer 2

Answer:

Optical communication utilizes the principle of total reflection. When the injection angle of light satisfies certain conditions, light can form total reflection in the optical fiber, thereby achieving the purpose of long-distance transmission.
