Question

how was the path of light ray in an optical fibre
​

Answer 1

Answer:

The light in a fiber-optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances.

Answer 2

Because they can walk in any kind of crooked path. The holes through the fibers are extremely fine.

Explanation:

• Light in a fiber-optic cable travels through the core (hallway) by continuously bouncing off the cladding (mirror-lined walls), a principle known as total internal reflection.
• Light travels down a fiber optic cable by repeatedly bouncing off the cable walls.
• Each light particle (photon) bounces down the pipe with a continuous internal mirror-like reflection.
• The light beam travels down the core of the cable.
• Light normally moves in straight lines, but it "bends" in an optical fiber.
