Question

A ray of light passes through a length of curved optical fibre. Draw a diagram showing the fibre and the path of the ray of light.

Answer 1

Explanation:

Diagram of total internal reflection in an optical fiber

Suppose you want to shine a flashlight beam down a long, straight hallway. Just point the beam straight down the hallway -- light travels in straight lines, so it is no problem. What if the hallway has a bend in it? You could place a mirror at the bend to reflect the light beam around the corner. What if the hallway is very winding with multiple bends? You might line the walls with mirrors and angle the beam so that it bounces from side-to-side all along the hallway. This is exactly what happens in an optical fiber.

Answer 2

Answer:

I can tell u the concept. its the Total internal reflection.

Explanation:

Draw a kind of pipe naming it as opt.pipe and incide a ray in it and then just demenstrate total internal reflection in it.

That simple.

Hope u understand.
