A) scattering
B) diffraction
C) polarization
D) multiple total internal reflections
Correct Answer: D
Solution :
An optical fibre is a device based on total internal reflection by which a light signal can be transferred from one place to the other with a negligible loss of energy. It consists of a very long and thin fibre of quartz glass. When a light ray is incident at one end A of fibre making a small angle of incidence. It suffers multiple total internal reflections and finally it reaches the point B.You need to login to perform this action.
