Light can be transmitted through long fiber optic strands because of
a. refraction.
b. external diffraction.
c. total internal reflection.
d. interference

Respuesta :

Answer:

(C) Total internal reflection

Explanation:

Total internal reflection :

  • It is the complete reflection of light in the medium ( medium may be glass ,water etc ) from the surrounding surface.
  • Total internal reflection occur when angle of incidence is greater than the limiting angle ( limiting angle is also known as critical angle ).
  • Light can be transmitted through long fiber optic due to total internal reflection

So the option (c) is the correct option
