Total internal reflection (T.I.R)||Deviation in T.I.R||Circle OF illumination||Continues variation OF R.I

Assertion : Optical fibres make use of total internal reflection. Reason : Light undergoes successive total internal reflections as it moves through an optical fibre.

Define total internal reflection. State its conditions. How do optical fibres transmit light without absorption.

Pick out the correct staments about optical fibres from the following: S1: Optical fibres are used for the transmission of optical signals only S2: Optical fibres are used for transmission of optical electrical signals S3: The intensity of light signals sent through optical fibres suffer very small loss S4: Optical fibres effectively employ the principle of multiple total internal reflections S5: Optical fibres are glass fibres coated with a thin layer of a material with lower refractive index

Conditions Of Total Internal Reflection

An optical fibre is made of glass fibre of refractive index 1.68. The outer coating of the glass fibre is made of material of refractive index 1.44. What is the range of angles of the incident rays with the axis of the pipe for which total internal reflection inside the optical fibre takes place?

Assertion : Optical fibers are used for telecommunication. Reason : Optical fibres are based on the phenomenon of total internal reflection.
